What do we call atoms of the same elements with different mass numbers?
Not all elements have the same mass numbers. Some elements have the same number of protons/electrons (atomic number) but have different number of neutrons causing different mass numbers. They are called isotopes of that element.Ex: Hydrogen has two isotopes, Deuterium and Tritium. They all have 1 proton and electron each, but have 0,1 and 2 neutrons respectively causing their mass numbers to be different.Atomic Number = Number of Protons/Electrons Mass Number = Atomic Number + Number of NeutronsHydrogen: Atomic number $=1$ Mass Number $=1+0=1$ Deuterium: Atomic Number $=1$ Mass Number $=1+1=2$ Tritium: Atomic Number $=1$ Mass Number $=1+2=3$

Adams of the same element broke with different mass numbers are called that strips isotopes have the same number of protons and the same number of electrons. But they have different number of neutrons, which leads to of the different no mass numbers of each of elements. So let's take a look at the hydrogen atom and it's isotopes. As an example, the regular hydrogen atom has one proton in zero neutrons, which leads to a mass number of one. The deuterium hydrogen isotope has one proton, as in the regular hydrogen eyes, too. But it has one neutron, which leads to a mass number of two. The treaty, um, Adam has one proton as to all hydrogen isotopes but has two neutrons, which leads to in mass number of three. Therefore, I strips have the same number of protons and elect drums, but a very number of neutrons, which leads to a different mass number
