Potassium has only one ‘valence electron’.
Option: B
Explanation:
- Sodium and potassium is in the same group of the ‘periodic table’. Sodium lies 11 in the ‘periodic table’.
- That means the ‘first orbital’ contains 2 electron the second orbital contains 8 electron and the last orbital or the valence orbital contains only one electron.
- Since sodium and potassium contains the same group the number of ‘valence electrons’ is same for the two elements. Hence potassium has ‘1 electron’ in the valence shell.
