(ii) What type of compounds can be formed by X and Y.
(iii) Write formula of the compound formed by X & Y.​

Answer 1

Explanation:

element X (atomic number 17) reacts with an element 1' (atomic number 20) to form a divalent halide.

(a) Where in the periodic table are elements X and Y placed?

(b) Classify X and Y as metal (s), non-metal (s) or metalloid (s)

(c) What will be the nature of oxide of element Y? Identity the nature of bonding in the compound formed

(d) Draw the electron dot structure of the divalent halide
