Answer:
Period 2 contains the elements which exist in all three states i.e. solid, liquid and gas.
Explanation:
- A periodic table is the tabular representation of chemical elements.
- Period 2 or group 17 contains the elements existing in all three states.
- It is the longest period which has halogens that have the following elements i.e.
Fluorine- ₈F exists in the gaseous state
Chlorine-₁₇Cl exists in the gaseous state
Bromine-₃₅Br exists in the liquid state
Iodine-₅₃I exists in the solid-state
Astatine-₈₅At exists in the Solid-state. (Radioactive element)
Since we can see the elements exist in all states i.e- solid (Iodine and Astatine), Liquid (bromine) and gaseous (Fluorine and chlorine), Period 2 is the correct one.
