Question

if I have the same number of protons and electrons, what type of charge would the atom have?

Answer 1

a proton has 1 unit of positive charge
an electron has 1 unit of negative charge

the resultant charge on an atom (more strictly "ion" if it has a charge) is got from adding all the charges.

so if there are equal positive and negative - what do you get when you add them?

(hint- what is +1 added to -1 ?)
