Question

1. which ionization energy and electronegativity periodic trends are demonstrated by group 15 elements from top to bottom? clear all the ionization energy increases, and the electronegativity decreases. the ionization energy decreases, and the electronegativity increases. the ionization energy increases, and the electronegativity increases. the ionization energy decreases, and the electronegativity decreases.

Explanation:

Ionization energy and electronegativity both decrease down a group in the periodic table. This is because as you move down a group, the out - most electrons are further from the nucleus and are shielded by more inner - shell electrons, making it easier to remove an electron (lower ionization energy) and less likely for the atom to attract electrons (lower electronegativity).

Answer:

The ionization energy decreases, and the electronegativity decreases.
