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..
No, isotopes of light elements exist as well. For example, there are several isotopes of the lightest element, hydrogen.No, even the lightest element (hydrogen (H)) has isotopes. These are called Deuterium and Tritium.All elements have isotopes but some of them are very unstable and have disappeared in nature over time.
No, they are different forms of the same element, so they are allotropes. Oxygen contains two atoms per molecule and ozone contains three atoms per molecule. Isotopes are atoms of the same element with different numbers of neutrons, such as oxygen-16 and oxygen-17.
Different isotopes of the same element are usually considered not to be chemically different. The atoms of different isotopes of the same element differ only in mass, not in their electronic structure, and it's the electronic structure of an atom that determines its chemical properties. A partial exception: hydrogen and its isotopes deuterium and tritium. Because the isotopes of hydrogen weigh twice and three times as much respectively, but have the same electronic structure, while they take part in the same chemical reactions, the reaction rates differ.
Hydrogen (H) (Standard atomic mass: 1.00782504(7) u) has three naturally occurring isotopes, denoted 1H, 2H, and 3H. Other, highly unstable nuclei (4H to 7H) have been synthesized in the laboratory but not observed in nature.Hydrogen is the only element that has different names for its isotopes in common use today. (During the early study of radioactivity, various heavy radioactive isotopes were given names; but such names are rarely used today). The symbols D and T (instead of 2H and 3H) are sometimes used for deuterium and tritium. IUPAC states that while this use is common it is not preferred.
That depends on the isotope, as Argon has three different stable isotopes and many different radioactive isotopes.
No - the lightest element Hydrogen has three known isotopes
The statement means that the element in question has three different forms (isotopes) with varying numbers of neutrons in their atomic nuclei. These isotopes of the element share the same number of protons and electrons but have different atomic masses due to the differing number of neutrons.

Isotopes have the same number of protons but a different number of neutrons. Different isotopes of a single element are on the same position on the periodic table of elements. The existence of isotopes was first suggested in 1913 by a radiochemist named Frederick Soddy.
No, they are different forms of the same element, so they are allotropes. Oxygen contains two atoms per molecule and ozone contains three atoms per molecule. Isotopes are atoms of the same element with different numbers of neutrons, such as oxygen-16 and oxygen-17.
Isotopes of promethium haven't special names. Promethium has 38 isotopes and isomers, all radioactive.Isotopes of all elements contain the chemical symbol of the element and:- as a superscript, to left: the mass number of the isotope- as a subscript, to left: the atomic number of the elementA correct symbol is not possible to be written on WikiAnswers window.
Hydrogen, Deuterium, Tritium
The three main isotopes of niobium are niobium-93, niobium-95, and niobium-96. These isotopes are stable and occur naturally in different abundances. Niobium-93 is the most abundant isotope, followed by niobium-95 and niobium-96.

They are isotopes of each other.
