Protons are havey and positively charged

Neutrons are havy and neutral

Electrons are tiny and negatively charged

Number of elcectrons EQUALS the Number of protons

Number of electrons always equals number of protons in a neutral atom

If electrons are added or removed the atom becomes charged and is then an ION
