Homework Answers
no net charge = no of protons are equal to the no of
electrons
anion means the more no of electrons than the protons so negative charge i.e anion formed
cation means the no of electrons are less than the protons and the positive charge is obtained
in an anion there are more electrons than the electrons giving the anion a negative charge
in non metals the no of electrons and the protons are same and there is no net charge
here the non metals are gains the electrons and then forms the anions and the no of electrons are more
if the same of no of electrons and the protons and there is no change in charge i.e no net charge
answers =>
in an anion there are more electrons than the electrons giving the anion a negative charge
in non metals the no of electrons and the protons are same and there is no net charge

We want to get better, more concrete
We want to get a better, more concrete idea of the strength of the electric force. So imagine you could remove all the electrons from 1 mL (1 cubic centimeter) of water. Dump the electrons on yourself, and put the electron-free nuclei (protons and neutrons) on the moon. Estimate how much force will there be between the positive and negative charges? (Of course you have to look up the earth-moon distance.) What fraction of your weight is that force?(How many...
