Here are the statements evaluated as true or false:
-
The nucleus of an atom is found in the atom's center.
True - The nucleus is indeed located at the center of an atom. -
The nucleus of an atom contains at least one proton.
True - By definition, a nucleus must contain at least one proton, making it a positive entity (except in the case of hydrogen-1, which has one proton). -
A neutron has a positive electrical charge.
False - Neutrons have no electrical charge; they are neutral. -
Most of an atom's mass is found in protons and neutrons.
True - The protons and neutrons account for the majority of an atom's mass, while electrons have negligible mass comparatively.
