Question

an Ion has a net charge of - 1 it has 18 electrons and 20 neutrons find the number of protons

Answer 1

Hi,

Here is your answer

Given net charge of ion = - 1
number of electrons = 18
The net charge is - 1 only when the number of protons is 17.
The number of protons = 17.

Hope this helps you.

Answer 2

the number of protons are always equal to the number of electrons but here ion charge is -1 so we subtract - 1 from 18 and the oxidation number of the element is minus 2 and the number of protons equals to 17 will help you and you will add this in brain list answer
