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.

Answer 1

92 U 232 92 U 238

In these uranium samples the electron and protons are the same = 92

but in first isotope the neutrons are =232-92=140

in case of second the neutrons are =238-92=146

now you can answer this question !

Answer 2

The answer is;  They each have the same number of protons

All uranium isotopes have 92 protons in their nucleus. However, they differ in the number of neutrons in the nucleus, hence this also translates to varying mass numbers (which is the sum of neutrons and protons in the nucleus). The most common isotopes of uranium are; U-238, U-235, and U-234.
