Given : two electrons are added to each of six atoms in a group.
removing two protons each from a group of six atoms.
To Find : net change in charge
Solution:
Proton
+ve in charge
Electric charge +1 e
electron
-ve in charge
Electric charge -1 e
Neutron
no charge
Electric charge 0 e
net change in charge if two electrons are added to each of six atoms in a group = + (-1 e) * 2 * 6 = - 12e
write an expression that represents removing two protons each from a group of six atoms. = - ( 1 e) * 2 * 6 = - 12e
net change in charge = -12e in both cases
