Question

elements that are characterized by the filling of p orbitals are classified as ___.

inner transition metals
groups 1a and 2a
groups 3a through 8a
transition metals

Explanation:

In the periodic table, elements in groups 3A through 8A (also known as the p - block elements) have their outermost electrons filling the p orbitals. Inner transition metals (f - block) fill f orbitals. Groups 1A and 2A (s - block) fill s orbitals. Transition metals (d - block) fill d orbitals.

Answer:

groups 3A through 8A
