WebFor cations that take on multiple charges, the charge is written using Roman numerals in parentheses immediately following the element name. For example, Cu (NO 3) 2 is copper (II) nitrate, because the charge of two nitrate ions ( NO− 3) is 2 × −1 = −2, and since the net charge of the ionic compound must be zero, the Cu ion has a 2+ charge. WebIt means that you have 3 OH (hydroxide) groups in the molecule. K3 [Fe (CN)6] means you have 6 CN groups and 3 K atoms. Hydroxide is in parentheses because there is a big …
