We make atomic number by number of protons in a atom. We make mass number by total of both protons and neutrons.

Atoms that have the same atomic numbers but different atomic weights are called what?

If they have the same atomic number but different mass, then they have a different number of neutrons, and they are called ISOTOPES.


How do you explain what does the atomic number stands for?

The atomic number is the number of protons in the atom.

Which refers to atoms with the same atomic number but different atomic masses?

They are called isotopes. eg we have different isotopes of carbon


What atoms has different masses but the same atomic number?

Isotopes of an element have different masses but the same atomic number. Isotopes have the same number of protons and electrons but different numbers of neutrons in their nuclei.


Atoms of the same atomic are called what?

isotopes Atoms of the same element are called Isotopes. they have the same number of atoms (i.e. same atomic number) but different number of neutrons


Can the neutral atoms of tow different element have the same number of electron explain?

NO. The number of electrons in any neutral atom must be the same as the number of protons. The number of protons is the atomic number, if the atomic number is the same then the atoms are of the same element, not different ones.


What do you called in an element having the same atomic number but different atomic masses?

Isotopes. eg U235 and U238. Both Uranium, atomic number 92, bur different isotopes.


If nuclides with the same atomic number but different mass number are called?

Isotopes


What are atoms with same atomic mass but different atomic numbers called?

Isotopes. The isotope has the same number of protons and electrons as the regular atom, but has more (or sometimes less) neutrons, and therefore its atomic mass is more (or less, depending on whether the neutrons have increased or decreased).


What are the atoms called then they have the same atomic number but different mass numbers?

They are called as isotopes in which mass number differ by emmision of radiation
