How do you do the stock method in chemistry?
The Stock Method of Naming The anion is named by taking the elemental name, removing the ending, and adding “-ide.” For example, F-1 is called fluoride, for the elemental name, fluorine. The “-ine” was removed and replaced with “-ide.” To name a compound, the cation name and the anion named are added together.
What is stock notation example?
Stock notation is the representation of oxidation number by putting a Roman numeral in parenthesis after the symbol of the metal in molecular formula. So, correct notation is NO2: Nitrogen (IV) oxide. FeCl3 is wrong because it should have been Iron (III) chloride and not Iron (II) chloride.

The Stock System of Nomenclature: Some elements (mostly transition metals) form two or more cations with different charges. To distinguish these ions, the Stock system of nomenclature is used. Put it together and you get copper (II) chloride. Two or more oxyanions are formed by the same two elements.

What is a chemical element?
Key Takeaways: Chemical Element Definition. A chemical element is a substance that cannot be further broken down by any chemical reaction. Each element has a unique number of protons in its atom. For example, a hydrogen atom has 1 proton, while a carbon atom has 6 protons. Varying the number of electrons in an atom of an element produces ions.
What are some examples of elements?
Examples of Elements. Any of the types of atoms listed on the periodic table is an example of an element, including: copper. cesium. iron. neon. krypton. proton - technically a lone proton qualifies as an example of the element hydrogen.
What are the elements of a chemical reaction?
Key Takeaways: Chemical Element Definition 1 A chemical element is a substance that cannot be further broken down by any chemical reaction. 2 Each element has a unique number of protons in its atom. For example, a hydrogen atom has 1 proton, while a carbon atom has 6 protons. 3 Varying the number of electrons in an atom of an element produces ions. Changing the number of neutrons produces isotopes. 4 There are 118 known elements.
How are elements formed?
Although elements aren't changed by chemical reactions, new elements may be formed by nuclear reactions. Elements are defined by the number of protons they possess. Atoms of an element all have the same number of protons, but they can have different numbers of electrons and neutrons.
Is a substance an element?
If more than one type of atom is present, a substance is not an element. Compounds and alloys are not elements. Similarly, groups of electrons and neutrons are not elements. A particle must contain protons to be an example of an element.
What is an Element in Chemistry?
An element is a substance made up of only one type of atom, all with the same number of protons. Pure gold is a famous example. A ring made of pure gold would be made of millions upon millions of atoms, each having 79 protons in its nucleus and thus having the same atomic number.
Parts of an Element: Periodic Table Information
On the periodic table, elements are classified into distinct types and some basic information is displayed about each of them. To learn the basics about a given element, simply look at its square on the periodic table.
Properties of Elements: What Makes an Element?
Now that we have defined the term "element," we should also take a look at the components that make up an atom of a given element. Atoms are made up of three types of subatomic particles: protons, neutrons, and electrons.
Why is it incomplete to name iron chloride?
To simply name this compound iron chloride would be incomplete because iron is capable of forming two ions with different charges.
What is the charge of copper ion?
Since the oxide ion is O 2-, the charges of the copper ion must be 1+ in the first formula and 2+ in the second formula. In the third formula, there is one tin ion for every two oxide ions. This means that the tin must carry a 4+ charge, making the name tin (IV) oxide.
Abundance
The elements vary widely in abundance. In the universe as a whole, the most common element is hydrogen (about 90% of atoms), followed by helium (most of the remaining 10%). All other elements are present in relatively minuscule amounts, as far as we can detect.

An element is the basic chemical building block of matter; it is the simplest chemical substance.
What is an element?
The periodic table of the chemical elements. In chemistry, an element is a pure substance consisting only of atoms that all have the same numbers of protons in their atomic nucle i. Unlike chemical compounds, chemical elements ...
What is the atomic number of an element?
Main article: Atomic number. The atomic number of an element is equal to the number of protons in each atom, and defines the element. For example, all carbon atoms contain 6 protons in their atomic nucleus; so the atomic number of carbon is 6. Carbon atoms may have different numbers of neutrons; atoms of the same element having different numbers ...
How many protons does carbon have?
Thus, all carbon isotopes have nearly identical chemical properties because they all have six protons and six electrons, even though carbon atoms may, for example, have 6 or 8 neutrons. That is why the atomic number, rather than mass number or atomic weight, is considered the identifying characteristic of a chemical element.
What are the two elements that are found in the universe?
The lightest chemical elements are hydrogen and helium, both created by Big Bang nucleosynthesis during the first 20 minutes of the universe in a ratio of around 3:1 by mass (or 12:1 by number of atoms), along with tiny traces of the next two elements, lithium and beryllium. Almost all other elements found in nature were made by various natural methods of nucleosynthesis. On Earth, small amounts of new atoms are naturally produced in nucleogenic reactions, or in cosmogenic processes, such as cosmic ray spallation. New atoms are also naturally produced on Earth as radiogenic daughter isotopes of ongoing radioactive decay processes such as alpha decay, beta decay, spontaneous fission, cluster decay, and other rarer modes of decay.
What are the main articles of isotopes?
Isotopes. Main articles: Isotope, Stable isotope ratio, and List of nuclides. Isotopes are atoms of the same element (that is, with the same number of protons in their atomic nucleus ), but having different numbers of neutrons. Thus, for example, there are three main isotopes of carbon.
What does "known" mean in chemistry?
In this context, "known" means observed well enough, even from just a few decay products, to have been differentiated from other elements. Most recently, the synthesis of element 118 (since named oganesson) was reported in October 2006, and the synthesis of element 117 ( tennessine) was reported in April 2010.
Which element has a half life?
Some of these elements, notably bismuth (atomic number 83), thorium (atomic number 90), and uranium (atomic number 92), have one or more isotopes with half-lives long enough to survive as remnants of the explosive stellar nucleosynthesis that produced the heavy metals before the formation of our Solar System.
When was Stock's system adopted?
In his own words, he considered the system to be "simple, clear, immediately intelligible, capable of the most general application.". In 1924, a German commission recommended Stock's system be adopted with some changes.
When did stock approve Roman numerals?
In 1934, Stock approved of the Roman numerals, but felt it better to keep the hyphen and drop the parenthesis. This suggestion has not been followed, but the Stock system remains in use world-wide. How do we name compounds when the cation of variable charge is involved?
What is feedstock in chemistry?
In chemistry, a feedstock is a chemical used to support a large-scale chemical reaction. The term usually refers to an organic substance. Also Known As: A feedstock may also be called a raw material or unprocessed material. Sometimes feedstock is a synonym for biomass.
What is a feedstock?
in biomedical sciences and is a science writer, educator, and consultant. She has taught science courses at the high school, college, and graduate levels. A feedstock refers to any unprocessed material used to supply a manufacturing process.
Why are feedstocks bottleneck assets?
Feedstocks are bottleneck assets because their availability determines the ability to make products. In its most general sense, a feedstock is a natural material (e.g., ore, wood, seawater, coal) that has been transformed for marketing in large volumes.
Is crude oil a feedstock?
Specifically , crude oil is a feedstock for the production of gasoline. In the chemical industry, petroleum is a feedstock for a host of chemicals, including methane, propylene, and butane. Algae is a feedstock for hydrocarbon fuels, Corn is a feedstock for ethanol.
