Question

There are three known forms of uranium. These forms are called _____ of each other.

Answer 1

isotopes, they have the same proton number but different nucleic numbers but are the same form

Answer 2

Isotopes

Step-by-step explanation:

Isotopes are atoms of a chemical element where their nuclei have the same atomic number, so isotopes of a given element have the same number of protons (Z), but have masses in different numbers (A).

Isotopes are species of the same element, with equal atom numbers and different masses, so they are different in number of neutrons, but with numbers of equal electrons and protons.
