Uranium is an element that is often used in nuclear power plants. Uranium atoms are very large, and the substance can be dangerous if it is not carefully contained.

Question

What is true about all uranium atoms?

They each have the same number of nuclear particles.
They each have the same number of neutral particles.
They each have the same number of neutrons.
They each have the same number of protons

Answer 1

The statement that is true about all uranium atoms is:

They each have the same number of protons.

Uranium has an atomic number of 92, which means all uranium atoms have 92 protons in their nuclei. However, uranium can exist in different isotopes, which means they can have different numbers of neutrons. Therefore, the other statements are not true for all uranium atoms.
