do isotopes have to be stable?
152102
Stable isotopes do not decay into other elements. In contrast, radioactive isotopes (e.g., 14C) are unstable and will decay into other elements. ... The chemical bonds and attractive forces of atoms with heavy stable isotopes are stronger than those in the more common, lighter isotopes of an element.

Isotopes are atoms of the same element that contain an identical number of protons, but a different number of neutrons. Despite having different numbers of neutrons, isotopes of the same element have very similar physical properties.

The atoms of a chemical element can exist in different types. These are called isotopes. They have the same number of protons (and electrons), but different numbers of neutrons. Different isotopes of the same element have different masses.

Atoms of the same element can have different masses. Isotopes of the same element can have different numbers of protons.

In the case of beryllium, a light metal, only the beryllium-9 isotope is stable with its 9 nucleons (i.e. 4 protons and 5 neutrons). All other beryllium isotopes decay after a certain amount of time.

16. Can two atoms with the same mass number ever be isotopes of each other? Explain. No- if they have the same mass number & different atomic numbers they are atoms of different elements.

Isotopes are atoms of an element with the normal number of protons and electrons , but different numbers of neutrons.

Nuclear stability. Of the six alkaline earth metals, beryllium, calcium, barium, and radium have at least one naturally occurring radioisotope; magnesium and strontium do not.

This is not easy. For many of the chemical elements there are several known isotopes. Isotopes are atoms with different atomic masses which have the same atomic number. The atoms of different isotopes are atoms of the same chemical element; they differ in the number of neutrons in the nucleus.

Atoms of the same element that differ in their numbers of neutrons are called isotopes. Many isotopes occur naturally. Usually one or two isotopes of an element are the most stable and common. Different isotopes of an element generally have the same physical and chemical properties.

Atoms of a particular element must have the same number of protons but can have different numbers of neutrons. When an element has different variants that, while all having the same number of protons, have differing numbers of neutrons, these variants are called isotopes.

An isotope is a group whose constituents belong to the same chemical element but have different mass numbers. Carbon has two isotopes: 12C and 13C. Both show the same chemical features because of the same atomic number. But the mass of 13C is larger than that of 12C, because 13C has one more neutron.

Which means it's no longer carbon because carbon atoms always have six protons. ... With 92 protons and upwards of 140 neutrons, uranium atoms are massive. And no isotopes of uranium are stable — they're all radioactive.

Nuclei of lithium can have 3, 4 or 5 neutrons. We call these different isotopes of lithium. Since different isotopes of an element have different numbers of neutrons (but always the same number of protons) they have different mass numbers. ... Lithium-6 and lithium-7 are both stable isotopes of lithium.

These different kinds of the same element are called isotopes. Isotopes are atoms that have the same atomic number (and are therefore of the same element) but different mass numbers.

Isotopes are atoms of the same element that have different numbers of neutrons but the same number of protons and electrons.

Isotopes are forms of a chemical element that have the same atomic number but differ in mass. 16O → 8 protons + 8 neutrons; a “light” oxygen); The relative amounts are expressed as either 18O/16O or δ 18O Oxygen - 18 (aka 18O → 8 protons + 10 neutrons; a “heavy” oxygen).
