Question

the mass number of atomic number of chlorine is 35.5 and 17 respectively find its number of neutron and how are electrons distributed in shell Cl 17​

Answer 1

Explanation:

Mass no.=35.5

Atomic no.=17

No. of neutrons=mass no.- atomic no.

35.5g is the average atomic mass of Cl...

It has 2 isotopes(Cl-35  and Cl-37)

no. of neutrons in Cl-35=35-15=18

no. of neutrons in Cl-37=37-17=20

electrons are distributed in K,L,M shells

2 in L, 8 in L, 7 in M.....

Hope it helps...
