Answer 1

Answer:

The ability of inner orbital electrons to repel the incoming electrons is called effective nuclear charge.

Explanation:

All electrons have a negative charge and therefore repel each other. Inner shell electrons repel valence electrons and thereby shield them to some extent from the attraction they experience towards the positively charged nucleus. The pull experienced by a valence electron is sometimes called the effective nuclear charge, as distinct from the actual nuclear charge. That's why elements on the far left of the periodic table are in general more likely to give away electrons, while elements on the far right are in general more likely to take them.
