Detailed explanation-1: -Thus, there is only one electron present in the outermost shell of Sodium.
Detailed explanation-2: -The outermost shell of the sodium ion is the second electron shell, which has eight electrons in it.
Detailed explanation-3: -A sodium atom has one electron in its outer shell. The atom is more stable if it has a full outer shell. A sodium atom can lose its outer electron.
Detailed explanation-4: -The “+1” tells us that it is missing one electron. The positive charge results from there being more protons than electrons. Since each electron has a “-1” charge, one electron has left the sodium atom. So it now has 10 electrons.
Detailed explanation-5: -A neutral sodium atom, for example, contains 11 protons and 11 electrons. By removing an electron from this atom we get a positively charged Na+ ion that has a net charge of +1. Atoms that gain extra electrons become negatively charged.
