- 1neutral (N/A)The number of electrons surrounding the nucleus of an atom is exactly equal to the number of protons in the nucleus. As a result, atoms are charge neutral (have no charge.
- 2nuclear reaction (N/A)Emission of electromagnetic radiation or particles is known as a nuclear reaction.
- 3nuclear radiation (N/A)The term nuclear radiation describes any rays or particles emitted (released) by atomic nuclei.
- 4balanced formula equation (N/A)In any balanced chemical equation the number of atoms of each element must be the same on both the reactant and product side of the equation.
- 5formula (N/A)Chemical symbols written (NaCl > Sodium Chloride).
- 6nucleusThe centre of an atom is called a nucleus.
- 7alpha particlesAn alpha particle is a cluster of two protons and two neutrons.
- 8beta particlesBeta particles are identical to electrons and therefore are very small and have a negative charge.
- 9gamma raysSometimes the protons and neutrons simply rearrange inside the nucleus but do not emit a particle but a form of electromagnetic wave known as gamma rays.
- 10reactantsThe original substances are called the reactants.
