An arrow with a Greek letter naming the decay mode.
Also known as: Decay equation notation, Alpha decay arrow
A decay is written as an arrow from parent to daughter with the emitted particle named — alpha, beta-minus, beta-plus or gamma. The mode determines what changes: alpha decay moves two places down the periodic table, beta decay moves one place up or down, and gamma decay moves nowhere.
Writes a radioactive decay as an arrow from parent nuclide to daughter with the emitted radiation named.
Contexts: Laboratory
Encodes what changes in the mode: alpha emission reduces the atomic number by two, beta emission changes it by one in either direction, and gamma emission changes it not at all.

A horizontal arrow between two nuclide symbols with a Greek letter written above or after it.
