How cations form
Web5 de mai. de 2024 · A cation is an ionic species with a positive charge. The word "cation" comes from the Greek word "kato," which means "down." A cation has more protons than electrons, giving it a net positive charge. Cations with multiple charges may be given special names. For example, a cation with a +2 charge is a dication. One with a +3 charge is a … Web22 de jul. de 2024 · Cations form from the loss of electrons and have a positive charge while anions form through the gain of electrons and have a negative charge.
