Praxis 5005 Practice Question
Which of the following is true about the nucleus of an atom?
Correct Answer: D
Rationale: The nucleus of an atom is composed of protons and neutrons, making option D accurate. Protons carry a positive charge, while neutrons are neutral, contributing to the overall positive charge of the nucleus.
Option A is incorrect as the nucleus has a positive charge due to the presence of protons. Option B is misleading; while neutrons are neutral, the overall nucleus is not neutral because of the protons. Option C is false since electrons are located outside the nucleus in electron shells, not within it. Understanding these distinctions is key to grasping atomic structure.
