I don't know about chromophores, but anions are always negative and cations are always positive. The way my teacher had us remember is that 'cat'ions are always 'paw'sative.
A positive ion is called a cation.
positive ions are called cations, while negatively charged ions are called anions
A cation is an ion that carries a positive charge & can combine with certain anions. The charge depends on the metals used.
Cation Mg2+ , anions 2 Cl-
Cations and anions are different types of ions.A cation is a positively charged atom or group of atomsA anion is a negatively charged atom or group of atomstotal positive charge of cations = total negative charge of anions
Cations are always positive, anions are negative.

They have opposite charges. A cation has a positive (+) charge; an anion has a negative (-) charge.
Cation Mg2+ , anions 2 Cl-
it is written as the chemical initial with a + next to it for example, hydrogen would be H+ ion.

Cations are always positive, whatever they're of. Ooh, or is that anions? Yeah, on second thoughts I think cations are negative. Hang on a minute, I'll check......nope, I was right first time. Cations are positive.
Aluminium, like most metals, forms cations easier than it does anions. The most common for aluminum is Al3+, when it has lost three electrons.
