Is a Copper (II) Ion mean it is Cu2+ or Cu2-? or neither?
does the roman numeral have anything to do with the numerical value for the charge? Thanks guys.
Answer:
Copper is a metal. It loses electrons, becoming positive. Copper II is what, in the old days we called Cupric, is +2.
yes, that´s exactly what the roman numeral means. about the + or -, the other guy´s right, i can´t put it better, no need to repeat.
All transition elements have a positive charge. The (II) or +2 represents the oxidation state of copper.
Alex,
Yes, the roman numeral on a metallic cation always represent the charge. Since metals always lose elecrons to form positive ions, the copper (II) ion is Cu2+.
all the previous answers are correct but coppper has another oxidation state, copper(I).
