A positively charged ion is called a/an:

Correct option is B

The correct answer is (b) cation.
· A positively charged ion is called a cation. Cations are formed when an atom or molecule loses one or more electrons, resulting in a net positive charge due to the excess of protons.
· This process typically occurs during chemical reactions where atoms donate electrons to achieve a stable electron configuration.
Explanation of Other Options:
· Anion: Incorrect, as an anion carries a negative charge.
· Molecule: Molecules can be neutral or charged, but they are not specifically defined as positive or negative.
· Atom: Atoms are neutral unless they gain or lose electrons, becoming cations or anions.
