Question

HELP PLEASE

Based on the organization of the Periodic Table of the Elements, what kind of bond does
chlorine form with both sodium and potassium?
A)ionic
B)metallic
© covalent
D)hydrogen

Answer 1

a) ionic

chlorine is present in top of group 17 and right of period 3 and

electronegativity(the tendency to gain electrons)

increases up the group and right the group.

so it has high tendency to form anion.

In the same way both Na and K are present up the group and left side and the tendency to lose electrons in both becomes high and they tend to form cation.
