Tell how each element below will fill its outer energy level and achieve a stable electron configuration in an ionic bond.


How will Francium (Fr) achieve a stable electron configuration?

a.It will lose 1 valence electron.
b.It will lose 2 valence electrons.
c.It will lose 3 valence electrons.
d.It will gain 3 valence electrons.
e.It will gain 2 valence electrons.
f.It will gain 1 valence electron

Fr is located in Group 1 (Alkali Metals) of the periodic table, meaning it has 1 valence electron in its outer energy level. In order to achieve a stable electron configuration, it will need to lose this valence electron.

Therefore, the correct answer is:

a. It will lose 1 valence electron.
