How does electronegativity generally change when moving down a column (group) on the periodic table?

Answer

It decreases because valence electrons are in higher energy shells further from the nucleus.

Moving down a group increases the distance between the valence electrons and the nucleus, leading to shielding effects and a decrease in electronegativity.
