the electrical charge of an atom is ___.
○ positive
○ negative
○ the atom has no charge, it is neutral

Explanation:

First Question (Which particle contributes the most to the electrical charge of the nucleus?):

• Protons have a positive charge, neutrons have no charge, and electrons are outside the nucleus. So protons in the nucleus contribute to its electrical charge. Neutrons are neutral, and electrons are not in the nucleus. Thus, the proton is the particle that contributes to the nucleus's electrical charge.

• In a neutral atom, the number of protons (positive charge) equals the number of electrons (negative charge). So their charges cancel out, making the atom electrically neutral (no net charge).

Answer:

A. proton

Second Question (The electrical charge of an atom is ___):
