Answer:

Hey,

Electronic configuration of X – 2,8,8,2

Electronic configuration of Y – 2,8,7

Molecular formula –

X Y

2 1

xy _{2}xy

Nature of bond -

The elements are Calcium and Chlorine....

"Calcium and Chlorine form an ionicbond in which Calcium donates an electron to Chlorine so that each atom can acquire a full valence shell.Calcium will donate two electrons, each goes to one Chlorine molecule therefore giving the resulting ionic compound a formula of CaCl2."

Hope it helps.

Plz mark it as brainliest.
