How do you find number of electrons in periodic table or how do you calculate the number of electrons?
A neutral atom has the same number of electrons as it does protons. The atomic numbers on the periodic table for each element are the number of protons. So, look up the element on the periodic table, note its atomic number, and you will then know the number of protons and electrons in a neutral atom of that element. For example, magnesium (Mg) has atomic number 12. So a neutral Mg atom would have 12 protons and 12 electrons.
