What happens when chlorine atom gains an electron in its outer energy shell?

Explanation:

Atomic number of chlorine is 17 and its electronic configuration is as follows.

Since, to become stable in nature chlorine requires only one electron from a donor atom.

As it is known that species that gain electrons will obtain a negative charge and species that lose electrons will obtain a positive charge.

Hence, when chlorine will gain an electron to become stabilized then it will change into chlorine ion or ion.

h let me think

a. the law of proportion states the combination of 2 atoms in a specific ratio to produce multiple compounds such as the given statement of question ‘1st compound contains 88.8 % cu ’ indicates 88.8 g of cu is present along with 11.2 g oxygen in 100 g of compound whereas the statement ‘2st compound contains 79.9 % cu ’ indicates 79.9 g of cu is present along with 20.1 g oxygen in 100 g of compound

1st compound contains 88.8 g cu

for cu

m = 63 g /mol

atomic % = 88.8 /63 = 1.42

for o

m = 16 g /mol

atomic % = 11.2 /16 = 0.7

b. the emperical formula of 1st compound is

cu1.4o0.7
