At a sufficiently high temperature you get a substance called plasma which contains no atoms; it consists of fragments of atoms.

The vibrating atoms/molecules in the hot sustance make the atoms/molecules in the cooler substance vibrate and this vibration gradually spreads along the substance.
The total kinetic energy of a substance's atoms is the sum of the kinetic energies of all the individual atoms in the substance. It is a measure of the overall motion of the atoms within the substance.
The Avogadro Number , which is 6.022 x 10^(23) atoms/molecules make one mole.
When all atoms in a substance are alike, the substance is an element. Each element is composed of atoms that have the same number of protons in their nucleus.

All matter is made of atoms. Liquids, solids and gases are all made of atoms. It is the bond between atoms that make a substance solid or liquid.
A substance in which all atoms are identical is called an element.
The smallest unit,usually consisting of a group of atoms,into which a substance can be divided without a change in its chemical nature.
All substances are made up of atoms. Atoms are the basic building blocks of matter and are composed of protons, neutrons, and electrons. These atoms combine to form molecules, which make up different substances.
