Question

An ____,or an element located in group 7A, will form a salt when reacted with a metal atom.

A. Alkali metal
B. Halogen
C. Noble gas
D. Transition metal

Answer 1

B. Halogen

Step-by-step explanation:

Halogens are the family of chemical elements found in the group VIIA of the periodic table which means they possess seven (7) outer electrons. Some examples of halogens are Fluorine (F), Iodine (I), Bromine (Br), and Chlorine (Cl).

A halogen, or an element located in group 7A, will form a salt when reacted with a metal atom.

For example, when Chlorine reacts with Sodium it would form a salt known as Sodium Chloride.

Na + Cl ----> NaCl
