Answer:

i hope it is help full ;

Explanation:

ANSWER

Relative atomic mass of chlorine is 35.5. Its atomic mass is relative because chlorine exists in two isotopes having an atomic mass number of 35 and 37 in the ratio 3:1. This is because its relative atomic mass is 35.5. Chlorine exists as a diatomic element because they don't have full valence shells on their own. thus it exists to have a diatomic element to have noble gas configuration i.e complete octet. Other diatomic element are Br,I,N,Cl,H,O,F etc
