Correct answer: A. Salt formers
- A. Salt formers
- B. Rare earth elements
- C. Alkali metals
- D. Noble gases
Explanation
Halogens are known as salt formers because they react with metals to form salts. For example, sodium chloride (NaCl), commonly known as table salt, is formed by the reaction of sodium (Na) with chlorine (Cl).

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.
