what type of ion has lost an electron and, consequently, has a net positive charge?\no isotope\no isomer\no…

Brief Explanations:

An isotope is an atom with the same number of protons but different numbers of neutrons. An isomer is a molecule with the same molecular formula but different structural arrangements. A cation is an ion that has lost one or more electrons, resulting in a net positive charge. An anion is an ion that has gained one or more electrons, resulting in a net negative charge.

Answer:

C. Cation
