Question

47. Electronic configurations of three elements X, Y and Z are as follows:

X- 2, 8, 1

Y - 2,8,7

Z- 2,8, 4

(a) Which of these is an electropositive element? (b) Which of these are electronegative elements?

(c) What will be the formula of the molecule formed between the atoms of Y? State the nature of the bond formed

(d) What will be the formula formed when Y combines with Z? State the nature of the bond formed.​

Answer 1

Answer:

1. Electropositive elements tend to lose electrons and form positive ions, e.g. the univalent alkali metals Li+, Na+, K+, etc., and the divalent alkaline-earth metals Be2+, Mg2+, Ca2+.
