Answer:

1 positively charged sodium ion

2 sodium ion that has lost an electron

Explanation:

Sodium is represented by the symbol Na. It has an atomic number of 11. In neutral state, it has 11 protons and 11 electrons. The electron shells are filled in the order 2,8,1. Thus, one electron remains in the outermost shell. To achieve stable state, Na loses one electron. The result is the formation of sodium ion which has one positive charge and which denotes the loss of one electron.
