What is the oxidation number of W in WO4-2?
In anions that contain oxygen along with a less electronegative element, each oxygen atoms is assigned an oxidation number of -2. Therefore, a WO4-2 anion requires the tungsten atoms to have an oxidation number of +6, to result in the specified charge of the anion.
Why do elements in group 2 have an oxidation number of -1?
They do not. The group 2 elements, Be, Mg, Ca etc, have oxidation numbers of +2.
What is the oxidation number for group 2 elements?
Hydrogen has -1 and +1 oxidation numbers. Other elements have +1 only
What are the oxidation numbers of the elements found in MgO?
+2 for Mg and -2 for O
What are the oxidation numbers of the elements in Fe2O3?
study island answer is +3 -2

What is the oxidation number of Ca(NO3)2?
The sum of the oxidation numbers is zero for the compound.
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 are three elements that have more than oxidation number?
Common examples include many nonmetals as sulfur which bears oxidation numbers varying from -2 to +6 in forming compounds. In oxychlorides, the oxidation number of chlorine atom(s) vary from -1 to +7. Many transition elements also bear different oxidation numbers. Copper has two ions: Copper(I) which is colorless and Copper(II) which is pale blue.
What is the oxidation numbers of CaBr2 2Na?
This is a compound. Compounds don't have oxidation numbers, only their constituent elements do. If you must have an answer, use 0.
