Answer 1

The atomic nucleus is the positively charged region at the center of an atom and contains most of the atom's mass.

Step-by-step explanation:

The atomic nucleus is the positively charged region at the center of an atom. It consists of protons, which have a positive charge, and neutrons, which have no charge. The nucleus contains most of the atom's mass because protons and neutrons are much heavier than electrons.
