a. halogen.
b. metalloid.
c. transition metal.
d. alkaline-earth metal.

Answer 1

A salt could be formed by an alkali metal and a halogen. The answer is letter A. A halogen is example of nonmetal. The answer is letter A. When compounds containing halogens they are called salts thus the name “salt – former”. Halogen consists of Fluorine, Chlorine, Bromine, Iodine, Astatine.

Answer 2

Answer is (A) - halogen.

Salts are inorganic and ionic compounds which are made from two ions. One is cation which has a positive charge and other one is anion which carries a negative charge. The overall charge of the salt is zero means the salt is neutral.

Alkali metals form salts with halogens like F, Cl, Br, and I. Here, the cation is alkali metal and halogen is the anion.
