For chlorine Z=17,A =35.Give the number of protons ,electrons and neutrons in (i)chlorine atom ,(ii) chloride ion.

Text Solution

Verified by Experts

In chlorinne atom (CI)
Number of protons (z)=17
Number of neutrons =A-Z=35-17=18
In chloride ion `(CI^(-))`
Number of protons (Z=17)
Number of electrons=(Z+1)=17+1=18
Number of neutrons =A-Z=35-17=18
