Isotope (Breast Cancer)

One of a series of chemical elements that have almost identical chemical properties but have different atomic weights and electric charge.

Isotope (Chemistry)

A variety of an element characterized by a specific number of neutrons in the nucleus.

Isotope (Climate)

One of two or more atoms that have the same atomic number (i.e., the same number of protons in their nuclei) but have different mass numbers.

Isotope (Electric Power)

An atomic form of an element having a particular number of neutrons. Different isotopes of an element have the same number of protons but different numbers of neutrons and hence different atomic mass, e.g.,. U-235, U-238. Some isotopes are unstable and decay to form isotopes of other elements.

Isotope (Environment)

A variation of an element that has the same atomic number of protons but a different weight because of the number of neutrons. Various isotopes of the same element may have different radioactive behaviors, some are highly unstable..

Isotope (Evolution)

An atom that shares the same atomic number and position as other atoms in an element but has a different number of neutrons and thus a different atomic mass.

Isotope (Geologic)

Different forms of a single element that have the same number of protons but different numbers of neutrons in their nuclei. Some radioactive isotopes are unstable and shed nuclear particles over time until they become stable. For instance, unstable isotopes of uranium break down to become lead.

Isotope (Microbiology)

Different form of the same element containing the same number of protons and electrons, but differing in the number of neutrons.

Isotope (Nuclear)

An atomic form of an element having a particular number of neutrons. Different isotopes of an element have the same number of protons but different numbers of neutrons and hence different atomic mass, e.g. U-235, U-238. Some isotopes are unstable and decay to form isotopes of other elements.

Isotope (Nuclear Science)

Isotopes of a given element have the same atomic number (same number of protons in their nuclei) but different atomic weights (different number of neutrons in their nuclei). Uranium-238 and uranium-235 are isotopes of uranium.

Isotope (Oceanography)

A different form of the same element, with a different number of neutrons in the nucleus.

Isotope (Physical Geography)

Form of an element where the number of neutrons in its atomic nucleus is different than the number of protons.

Isotope (Prostate Cancer)

A different form of a chemical element having similar properties

Isotope (Solar Physics)

One of two or more atoms having the same number of protons in its nucleus, but a different number of neutrons and, therefore, a different mass.
