Commence par A

The smallest unit of a chemical element, consisting of a nucleus and electrons.

Commence par B

A lasting attraction between atoms that enables the formation of chemical compounds.

Commence par C

A substance that increases the rate of a chemical reaction without being consumed.

Commence par D

Molecules composed of two atoms, which can be of the same or different elements.

Commence par E

A measure of an atom's ability to attract and hold onto electrons.

Commence par F

A metabolic process that converts sugar to acids, gases, or alcohol using microorganisms.

Commence par G

A state of matter characterized by low density and viscosity, and high compressibility.

Commence par H

The lightest and most abundant chemical element, often found in water and organic compounds.

Commence par I

An atom or molecule that has gained or lost one or more electrons, resulting in a charge.

Commence par J

A unit of energy in the International System of Units, often used in chemistry.

Commence par K

The study of the rates of chemical reactions and the factors affecting them.

Commence par O

A chemical reaction that involves the loss of electrons or an increase in oxidation state.

Commence par P

A scale used to specify the acidity or basicity of an aqueous solution.

Commence par Q

A fundamental particle and a basic constituent of matter, combining to form protons and neutrons.

Commence par R

A substance used to cause a chemical reaction or to test for the presence of another substance.

Commence par S

A substance that dissolves a solute, forming a solution, often a liquid.

Commence par T

A technique used to determine the concentration of a solute in a solution by adding a reagent.

Commence par U

A heavy metal used as fuel in nuclear reactors and in the production of nuclear weapons.

Commence par V
