For the reaction, (where X is halogen)2M + X2 -> 2MXIf M is metal, it is more likely to be:
Correct answer: B. Alkali Metal
- A. Alkaline earth metal
- B. Alkali Metal
- C. Outer transition metal
- D. Inner transition metal
- E. None of the above
Explanation
If X is a halogen this means X has an oxidation of -1. Since the compound formed when X reacts with halogen to form MX, the M has an oxidation state of +1. Alkali Metals have an oxidation state of +1.

About s-Block and p-Block Elements
The s and p blocks are studied through their valence-shell configurations, periodic trends and characteristic chemical properties. Work covers the reactions of Group I and Group II elements, the behaviour of Group IV elements, and how atomic size, ionization energy, electronegativity and metallic character change across periods and down groups.
