absolute zero- Absolute zero is 0K. It is the lowest possible temperature. Theoretically, at absolute zero, atoms stop moving. accuracy- Accuracy is a measure of how close a measured value is to its true value. For example, if an object is exactly a meter long and you measure it as 1.1 meters long, that is more accurate than if you measured it at 1...
base - A base is a compound that produces OH- ions or electrons in water or accepts protons. An example of a common base is sodium hydroxide, NaOH. beta particle - A beta particle is an electron, although the term is used when the electron is emitted in radioactive decay. binary compound - A binary compound is one made up of two elements. binding e...
delocalization- Delocalization is when electrons become free to move all over a molecule, such as when double bonds occur on adjacent atoms in a molecule. denature - There are two common meanings for this in chemistry. First, it can refer to any process used to make ethanol unfit for consumption (denatured alcohol). Second, denaturing can mean brea...
family - A family is a group of elements sharing similar properties. It is not necessarily the same thing as an element group. For example, the chalcogens or oxygen family consists of different elements from the nonmetal group. Kelvin - Kelvin is a unit of temperature. A Kelvin is equal in size to a degree Celsius, although Kelvin starts from absol...
node- A node is a location in an orbital with no probability of containing an electron. nucleon- A nucleon is a particle in the nucleus of an atom (proton or neutron). oxidation number The oxidation numberis the apparent charge on an atom. For example, the oxidation number of an oxygen atom is -2. period- A period is a row (left to right) of the pe...
salt- An ionic compound formed from reacting an acid and a base. solute - The solute is the substance that gets dissolved in a solvent. Usually, it refers to a solid that is dissolved in a liquid. If you are mixing two liquids, the solute is the one that is present in a smaller amount. solvent - This is the liquid that dissolves a solute in solutio...
unit cell- A unit cell is the simplest repeating structure of a crystal. unsaturated - There are two common meanings for unsaturated in chemistry. The first refers to a chemical solution that does not contain all the solute that can be dissolved. Unsaturated also refers to an organic compound with one or more double or triple carbon-carbon bonds. u...

- What does chemistry mean? As an introduction to chemistry, it is the branch of science that studies matter and change. First, chemistry deals with the study of the composition and the properties of matter (which is basically any macroscopic substance that we can observe).
- When was chemistry “discovered”? Very simple chemical processes were performed even during ancient history, at 1000 BC, much before any basic chemistry concepts or laws were actually established.
- Why is chemistry important? Everything is chemistry. Everything that you can observe macroscopically is made of chemicals. You are made of chemicals, your food is chemicals, you breathe chemicals, we live out of and thanks to chemicals, everything you see under the sun is a mixture of chemicals.
- Why is chemistry called central science? A all sciences are glued together by basic chemistry concepts, thats why it is called the central science. Without chemistry, physical sciences (which include chemistry itself), would find a gap and not be bound to life sciences (such as biology) and applied sciences (such as engineering).
This glossary of chemistry terms is a list of terms and definitions relevant to chemistry, including chemical laws, diagrams and formulae, laboratory tools, glassware, and equipment.
May 29, 2024 · This alphabetical chemistry dictionary offers definitions and examples of important chemistry and chemical engineering terms. For each term, a brief definition is given, and each link leads to a more comprehensive discussion of the word.
Feb 20, 2022 · At the heart of chemistry are substances — elements or compounds— which have adefinite composition which is expressed by a chemical formula. In this unit you will learn how to write and interpret chemical formulas both in terms of moles and masses, and to go in the reverse direction, in which we use experimental information about the ...
