MHT CET Chemistry Question (2026) — Solution

Question

What is the general formula of halide salts of alkali metals if M is a metal atom ?

Options

  1. A. MX
  2. B. MX _2
  3. C. M _3 X _2
  4. D. M _2 X _3

Answer

A. MX

Step-by-step solution

Alkali metals belong to Group 1 of the periodic table and have one valence electron. They lose this electron to form a unipositive ion, M^ + . Halogens belong to Group 17 and have seven valence electrons. They gain one electron to form a uninegative ion, X^ - . To form a neutral salt, one M^ + ion combines with one X^ - ion. The general formula of halide salts of alkali metals is MX. Answer: MX
