Select the correct answer.

Which pair of elements can form ionic bonds?

A. copper (Cu) and nitrogen (N)
B. gallium (Ga) and phosphorus (P)
C. hydrogen (H) and sulfur (S)
D. phosphorus (P) and fluorine (F)
E. potassium (K) and bromine (Br)



Answer :

Final answer:

Ionic bonds are formed by specific pairs of elements due to the transfer of electrons resulting in charged ions.


Explanation:

The pair of elements that can form ionic bonds is:

  1. Hydrogen (H) and sulfur (S)
  2. Phosphorus (P) and fluorine (F)

When these elements bond, one element gives up electrons (becomes positively charged), and the other gains those electrons (becomes negatively charged), resulting in the formation of ionic compounds.
