Question

atomic structure - show what you know
which of the following statements about neutrons is incorrect?
○ they have a mass of 1 amu
○ they are located in the nucleus
○ they have a charge of +1.
○ they hold the nucleus together.

Explanation:

1. Recall the properties of neutrons: Neutrons have a mass of approximately 1 amu, are located in the nucleus, and help hold the nucleus together (along with the strong nuclear force).
2. Neutrons are electrically neutral, meaning they have a charge of 0, not +1. The option "They have a charge of +1" is incorrect.

Answer:

The incorrect statement is: They have a charge of +1.
