Question

Which part of a helium atom is positively charged?

(1) electron (3) nucleus
(2) neutron (4) orbital

Answer 1

The correct answer is 3.

In any atom, the nucleus will be positively charged because the only ions in the nucleus are neutrons, which have a neutral charge, and protons, which have a positive charge.

Electrons are negatively charged, and they are in the orbital, thus making the orbital negatively charged.
