What do you mean by effective nuclear charge? Effective nuclear charge is the magnitude of positive charge in an atom from the pull on the valence electrons towards the positively charged nucleus. An increase in atomic number associated with a decrease in atomic radius will result in a higher ...

We need to take a quick look at the nuclear structure to understand what electron shielding is and how to calculate the effective nuclear charge. Here are the basics of the atomic orbital model first! An atom is composed by: A positively charged nucleus made of protons and neutrons. The num...
