Question

Element M is a metal that forms compounds of the type MX2, MX3, and MX4, where X is a halogen. What is the expected trend in the ionic radius of M in these compounds? Arrange these compounds in order of decreasing ionic radius of M.

Answer 1

Ans

MX2 ,MX3 .MX4

Explanation:

greater the positive charge  greater will be the nuclear pull and the valence shell will be pulled closer as a result size of cation decreases   i corrected the order ignore my previous message
