If this atom has 43 electron it must have 43 protons to be a neutral atom of no charge.
There are 19 protons in the potassium atom.
A Krypton atom has 36 protons and 36 electrons each.
Fluorine is a halogen gas. It has 19 protons in a single atom.

The number of protons in an atom is different for every element. If you look at the periodic table, then the number labeled "atomic number" is the number of protons.
7 protons
A neutral atom has as many electrons as protons. This is because protons have a positive charge and electrons have a negative charge, but because there are the same number of them, they cancel each other out.
Calcium: The identity of an element is determined by how many protons each atom of the element has, and calcium is the name of the element with 20 protons per atom.

Copper has 29 electons,29 protons,and 35 neutrons.
One - assuming the atom is not an ion.
The Answer is 4.....!
Two electrons to match the positively charged protons. Neutrons are neutral and add nothing either way to charge.
In one atom of Oxygen there are 8 electrons
