Question

Which of the following statements about neutrons is true

A : neutrons help make an atom more stable
B: isotopes if an element have the same number of neutrons
C: the number of neutrons in an atom determines what element it is
D: neutrons have much less mass than protons or electrons

Answer 1

The answer is A: neutrons help make an atom more stable.

Neutrons do not have a charge, and they weigh about the same as a proton. Neutrons make an atom more stable because they hold the protons together. Without neutrons, the protons would separate from each other.

The answer is A: neutrons help make an atom more stable.
