Concept explainers
Interpretation:
The charge carries by a nucleus and charge of an atom needs to be determined.
Concept introduction:
The nucleus of an atom consists of neutrons and protons. And the atom consists of neutron, protons, and electrons.
Answer to Problem 98A
The charge on the nucleus of an atom is positive and the atom is overall neutral.
Explanation of Solution
The nucleus contains the neutral neutrons and positive protons, which means the nucleus contains a positive nature particle, so it is positively charged.
The three subatomic particles are very important for deciding the electrical nature of an atom.
The central region of an atom is positive and the surrounded area is full of negative nature particle, so the atom having an equal and opposite charge. Therefore, it is electrically neutral.
The nucleus of an atom is consists of proton and neutron, so the nucleus is positive, and the atom is electrically neutral.
