Question

An element x forms a chloride with the formula xcl2 which is a solid with high melting point x would be most lightly to be in the ------ group guess the element and its valency. GUYS PLEASE ANSWER IT....​

Answer 1

according to question X must have valency 2 as it forms oxide of chloride with valency 2

given it is the most likely to win that group so

the group in which light lies is second

hope it helps

Answer 2

Explanation:

Elements of group NaNa form XClXCl hailde.

Elements of group MgMg form XCl_2XCl

2

hailde.

Elements of group AlAl form XCl_3XCl

3

hailde.

Elements of group SiSi form XCl_4XCl

4

hailde.

As element XX forms a chloride with the formula XCl_2XCl

2

, which is a solid with a high melting point. XX would most likely be in the same group of MgMg.
