同位素 Isotope

（重定向自Nuclear notation）
The three naturally-occurring isotopes of hydrogen. The fact that each isotope has one proton makes them all variants of hydrogen: the identity of the isotope is given by the number of neutrons. From left to right, the isotopes are protium (1H) with zero neutrons, deuterium (2H) with one neutron, and tritium (3H) with two neutrons.

同位素（英语：Isotope）是某种特定化学元素之下的不同种类，同一种元素下的所有同位素都具有相同原子序数，质子数目相同，但中子数目却不同。这些同位素在化学元素周期表中占有同一个位置，因此得名。

例如氢元素中，氕、氘和氚，它们原子核中都有1个质子，但是它们的原子核中分别有0个中子、1个中子及2个中子，所以它们互为同位素。

Isotope half-lives. The plot for stable isotopes diverges from the line Z = N as the element number Z becomes larger

Isotopes are variants of a particular chemical element which differ in neutron number, although all isotopes of a given element have the same number of protons in each atom. The term isotope is formed from the Greek roots isos (ἴσος "equal") and topos (τόπος "place"), meaning "the same place"; thus, the meaning behind the name is that different isotopes of a single element occupy the same position on the periodic table. The number of protons within the atom's nucleus is called atomic number and is equal to the number of electrons in the neutral (non-ionized) atom. Each atomic number identifies a specific element, but not the isotope; an atom of a given element may have a wide range in its number of neutrons. The number of nucleons (both protons and neutrons) in the nucleus is the atom's mass number, and each isotope of a given element has a different mass number.
