The smallest unit of an element that retains the chemical properties of that element. Atoms are composed of protons, neutrons, and electrons.

A group of two or more atoms held together by chemical bonds. Molecules can be composed of the same type of atom (e.g., O2, oxygen molecule) or different types of atoms (e.g., H2O, water molecule).

A substance composed of only one type of atom. Examples include gold (Au), silver (Ag), and oxygen (O).

A group of elements that are highly unreactive due to their full outer electron shells. They typically exist as isolated atoms in their natural state.

A substance composed of two or more different elements chemically bonded together. Examples include water (H2O), salt (NaCl), and sugar (C12H22O11).

A measure of how much matter an object contains. It is typically measured in kilograms (kg) or grams (g).

A measure of a substance's mass per unit volume. It is typically measured in kilograms per cubic meter (kg/m3) or grams per liter (g/L).

A measure of the distance traveled over a certain amount of time. It is typically measured in meters per second (m/s) or kilometers per hour (km/h).

A measure of how far apart two points are. It is typically measured in meters (m), kilometers (km), or miles (mi).

The amount of space occupied by a three-dimensional object. It is typically measured in cubic meters (m3) or liters (L).

The force exerted on an object by gravity. It is typically measured in newtons (N) and is directly proportional to the object's mass.

A measure of the average kinetic energy of particles within a system. It is measured in Kelvin (K) and is related to the random motion of particles.
