Explanation:

Anions have a negative charge resulting from the gain of one or more electrons to become stable.

Cations have a positive charge due to the loss of two or more electrons in order to become stable or have a noble gas configuration.

Some of this energy is emitted back from the Earth's surface in the form of infrared radiation. Water vapor, carbon dioxide, methane, and other trace gases in Earth's atmosphere absorb the longer wavelengths of outgoing infrared radiation from Earth's surface.
