Effective Nuclear Charge

During lecture one of the notes on the presentation stated, "Inner electrons shield outer electrons from electrostatic attraction of positive nucleus; outer electrons feel a reduced electrostatic attraction, results in an effective nuclear charge." Can anyone clarify what an effective nuclear charge is?

Effective nuclear charge is basically the attraction the valence electrons around the nucleus feel from it, so what Dr. Lavelle is saying is that the inner electrons 'shield' the amount of attraction the outer electrons feel from the nucleus, hence why it feels a lower electrostatic attraction.

It is also important to note that effective nuclear charge tends to increase as you move from left to right on the periodic table.
