Answer :

(B) It is likely to form ionic bonds

(D) It is in period seven

(E) It is a metal

Explanation :

Francium is an element whose symbol is 'Fr' and atomic number is 87.

Group 1 alkali metals consists elements Lithium, Sodium, Potassium, Rubidium, Caesium and Francium. Periodic table also shown below.

Francium belongs to the group 1 (alkali metal) and it is in period seven.

It has one valence electron, the electronic configuration of Francium is [Rn} .

Alkali metals have tendency to form ionic compounds because they have +1 charge.
