isotopes just mean they have a different number of neutrons so if the..
Mass number = # of protons + # of neutrons -they will have a different (greater) mass
Isotopes of the same element differ in the number of neutrons. Isotopes have different physical properties but similar chemical properties.
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..
number of neutrons, and therefore their mass numbers.
Such atoms are isotopes and belong to the same element.
We can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
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.
No they don't have. Isotopes of an element differ in mass from from each other and this is due to the different no. of electrons in their nucleus.
Isotopes of an element have the same number of protons but different numbers of neutrons. This results in variations in atomic mass for isotopes. The element atoms on the periodic table represent the average mass of all its naturally occurring isotopes.
Isotopes. They differ in the number of neutrons in the nucleus.
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,because in isotopes neutrons differ from normal element.
Isotopes have same number of electrons, same atomic no. but different mass no. They are from the same element like isotopes of carbon. They are not having same number of neutrons. They show same electronic configuration.
