Oxidation numbers for five common transition elements?
Transition elements usually have more than one oxidation number. In different oxidation numbers, the ions show different colors. Some of the ranges: Cu from +1 to +2; Cr from +2 to +6; Ni from +2 to +3; Co from +2 to +3 and Mn from +2 to +7.
What is the sum of the oxidation numbers for P2O5?
The sum of the oxidation numbers for P2O5 is zero. In P2O5, the oxidation number for phosphorus is +5, and each oxygen atom has an oxidation number of -2. Since there are five oxygen atoms, the total sum of the oxidation numbers is 2(+5) + 5(-2) = 0.
What are the oxidation numbers of Lead?
It depends on the compound. Lead can have an oxidation state of either 2+ or 4+
What do the oxidation number of 2 and -2 imply?
An oxidation number of 2 means the ion has two more protons than electrons. An oxidation number of -2 means the ion has two more electrons than protons.
What is the oxidation numbers in PO34?
