Work Step by Step

The number of protons and electrons in a neutral atom can be found by looking up the atomic number from a periodic table. If ions have a positive charge, then electrons are lost by that magnitude. If ions have a negative charge, then electrons are gained by that magnitude. The number of protons and electrons in a neutral atom can be found by looking up the atomic number from a periodic table.
