Variable Valence

Postby Myles Chang 1B » Sun May 20, 2018 12:36 pm


I was wondering if there was any way to tell how many electrons in the d-block are lost in an ion. For example, is there any way to know whether a copper atom will go to 3+ or 2+; if there is not, will be be given the charge on the test?

Based on the formula, you can find out the charge on the transition metal ions since compounds must be neutrally charged. Also, if the transition compound is named, the charge is specified by the Roman numeral. For example Cu(NO3)2 = Copper(II) nitrate
