An atom is made up of three fundamental particles:
- Protons are positively charged particles in an atom
- Electrons are negatively charged.
- Neutrons carry no charges.
In a neutral atom, the number of protons and electrons are the same and equal.
Most atoms are usually depicted this way:
ᵃₙX
where a is the mass number of the atom.
n is the atomic number
X is the symbol of the atom
The mass number is the sum of the number of protons and neutrons
Atomic number is the number of protons.
In a neutral atom, the atomic number is also the number of electrons since the atom is neutral. It has not gained or lost any additional electrons.
