An element is defined by the number of protons, so this cannot vary.
Isotopes of a particular element are different in the number of neutrons within the atoms. These isotopes are said to be comparatively "lighter" or "heavier" than other isotopes based on the total of protons and neutrons (Atomic Mass).
Yes, isotopes, different forms of one element, have the same number of protons in the nucleus (the same atomic number) and the same number of electrons, but a different number of neutrons (the same atomic mass).
yes, an isotope is an atom with a different number of neutrons but the same number of protons and electrons
Isotopes only differ in the number of neutrons. When this happens, the mass of the element changes.
No, all isotopes of an element have the same number of protons, they have different numbers of neutrons.
isotopes are atoms of same element having eqaul atomic no. but different mass no.
they can't differ in no. of protons
Yes, it is true.
Atoms of the same element with different atomic masses are known as isotopes. Isotopes differ only by the number of neutrons present in the nucleus of the isotopes. The number of protons is the same for all isotopes of an element (because if there were different numbers of protons, then the atoms would not be of the same element).
Isotopes of the same element have the same number of protons (atomic number) but differ in number of neutrons (hence atomic masses).
The isotopes of an element have the same number of protons, but different numbers of neutrons.
Isotopes of the same element differ in the number of neutrons. Isotopes have different physical properties but similar chemical properties.
Atoms of the same element that differ in the number of neutrons they contain are known as isotopes.
Isotopes
no isotopes of a particular chemical element all have the same number of protons
Isotopes have a different number of neutrons but the number of protons and electrons is the same.
Isotopes.
Isotopes.
Isotopes differ by the number of protons.
Isotopes of a given element all have the same number of protons. They differ in their number of neutrons.
Isotopes of an element have the same numbers of protons in the nucleus (and corresponding electrons). It's not so much "can have", as "do have". It's just a different number of neutrons that makes a different isotope.
Isotopes must have the same atomic number, which is the number of protons. The atomic mass, which is the total number of protons and neutrons, varies for the different isotopes. so it should have different mass numbers..
Yes, isotopes of an element are the same element but with different numbers of neutrons in the nucleus and thus different atomic masses.
Neutrons. If the differ in electrons they are not neutral and if they differ in protons then they are no longer the same element as the number of protons determines the name of the element.
Two isotopes of an element have the same atomic number (number of protons) but have different mass numbers (sum of protons and neutrons). This means that they will differ in the number of neutrons despite being the same element.
