The charge on the atom containing 17 protons, 18 neutrons and 18 electrons is :
Open in App
Solution
The correct option is C −1
Given, the number of proton, neutron, and electrons are
P=17,n=18,e=18
As in a normal element e = p but in ions it is not
As 1e more than p, so the charge = −1.
So, the correct option is C
