Coulombs Law describes the interaction between two charges and varies by the magnitude of these
charges and inversely with the distance between them.
For atoms, we'll label the charges as the
nuclear charge and electron charge.

As you go up in atomic number (Z), the number of protons in the nucleus increases, making the charge
on the nucleus increase, so that in general. qnuc
= Z ·(+1)
However if we think only of the electrons in the outermost shells (valence
electrons), they do not see the full strength of the nuclear charge because it
is partially shielded (or canceled out if you prefer) by the core electrons. So
we define something called effective charge.

Effective Charge = # of protons
Zeff = Z – core

In general, Zeff increases as you go across in the periodic table.
