They are called as isotopes in which mass number differ by emmision of radiation
No element has this atomic number. All atomic numbers are whole numbers.
The isotopes of the same element has the same atomic number. But the mass number (atomic mass) is different.
No, atomic number equals the number of protons.The number of neutrons is NOT specific to an element, and various atoms of the same element can have different numbers of neutrons - these are called isotopes.
Have different atomic mass (have different numbers of neutrons)
Atomic numbers are the number of protons and electrons in a atom.
If they have the same atomic number but different mass, then they have a different number of neutrons, and they are called ISOTOPES.
Because different elements have different numbers of protons, which determines the atomic number.
Atoms with the same atomic number (number of protons), but different mass numbers (i.e. different mass) are called isotopes. The difference in mass is due to different numbers of neutrons. For more info: http://en.wikipedia.org/wiki/Isotope
The different mass numbers are due to different numbers of neutrons.
Isotopes have different numbers of electrons, but not different atomic numbers (numbers of protons) or they'd be different elements.
If two atoms are isotopes, it means they have the same number of protons but different numbers of neutrons. Thus, they have the same atomic numbers, but different atomic masses.
isobars are elements with same mass numbers (Atomic Mass) and different atomic number (number of proton or electron)
Yes; isotopes of the same element have the same atomic number but differ in their atomic masses.
Yes. Isotopes have the same atomic number because all of their atoms have the same number of protons. They have different mass numbers because their atoms have different numbers of neutrons, and mass number is the sum of the numbers of protons and neutrons.
The big numbers are atomic numbers. They are equal to number of protons. Elements are arranged in order of increasing atomic number.
They have different numbers of neutrons.
