Question

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. 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.

Explanation:

All atoms of a specific element have a fixed number of protons, which defines the element's atomic number. Uranium has an atomic number of 92, so all uranium atoms have 92 protons. Isotopes of uranium exist with different numbers of neutrons (neutral particles), which changes the total number of nuclear particles (protons + neutrons).

Answer:

They each have the same number of protons.
