Chat with our AI personalities
For two isotopes to be of the same element it has to have the same atomic number and a different mass number. This means 3116X and 3216X are the same element.
It's either called a molecule or a chemical compound.
A molecule made up of two or more different elements is called a compound, whereas a molecule made up of two of the same elements is still just an element.
Isotopes are two or more forms of the same chemical element that differ in atomic mass due to having a different number of neutrons in their nuclei. These isotopes of an element have the same number of protons and electrons but vary in their overall mass.
