Question

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

Explanation:

Ionization energy and electronegativity generally decrease down a group in the periodic table. This is because as you move down a group, the atomic radius increases, the out - er electrons are further from the nucleus and are shielded by more inner - shell electrons. So, it is easier to remove an electron (lower ionization energy) and the atom has a lower ability to attract electrons (lower electronegativity).

Answer:

The ionization energy decreases, and the electronegativity decreases.
