Which of the following best describes the overall charge of an atom's nucleus?
A
Negative
B
Neutral
C
It depends on the number of neutrons
D
Positive
Verified step by step guidance1
Recall that the nucleus of an atom contains protons and neutrons.
Understand that protons carry a positive charge, while neutrons are electrically neutral (no charge).
Since the nucleus contains protons (positive charge) and neutrons (neutral), the overall charge of the nucleus depends on the number of protons only.
Therefore, the overall charge of the nucleus is positive because of the presence of positively charged protons.
The number of neutrons does not affect the charge, only the mass and stability of the nucleus.
