Which of the following best describes the overall charge of an atom's nucleus?
A
Positive
B
Negative
C
Neutral
D
It depends on the number of neutrons
Verified step by step guidance1
Recall that an atom's nucleus contains protons and neutrons. Protons carry a positive charge, while neutrons are electrically neutral.
Since neutrons have no charge, they do not affect the overall charge of the nucleus.
The overall charge of the nucleus is determined by the number of protons it contains because each proton contributes a positive charge.
Therefore, the nucleus has a net positive charge equal to the total number of protons.
This means the best description of the overall charge of an atom's nucleus is 'Positive'.
