Question

The atomic no of Al is 13 and that of Cl is 17.How many elctrons,protons,nutrons are present in Al3×and Cl'.

Answer 1

In Al3+ no of proton=13
No of electron=10
No of nuetron =27-13
14
In cl-
No of proton=17
No of electron= 18
No of nuetron =18

Answer 2

In Aluminium the no.of protons=13
The no.of electrons=13
The number of neutrons=27-13=14
In chlorine the no.of protons=17
The no.of electrons=17
The no.of neutrons=35.5-17=18.5
