Answer 1

Answer:

Atomic Number 20 is Calcium

Atomic Number 13 is Aluminium

Atomic Number 17 is Chlorine

Calcium(At. No. 20) will combine chemically with chlorine(At. No. 17) rather than with Aluminium(At. No. 13) because Chlorine will accept an electron from Calcium to form an ionic bond but Aluminum being a metal with 3 valance electrons will not accept an electron
