+1 for Rb
+1 for Cl
-2 for O
An element that tends to give up electrons has a positive oxidation number. This is because when an element loses electrons, it becomes positively charged.
In CrO3, the oxidation number of chromium (Cr) is +6 and the oxidation number of oxygen (O) is -2. This is because oxygen typically has an oxidation number of -2, and there are three oxygen atoms in CrO3 to give a total charge of -6. To balance the charge, the chromium atom must have an oxidation number of +6.
As SO42- has an overall -2 charge, The Oxygen has a -2 oxidation state, so to balance and give an overall -2 charge, the Sulfur has to have a +6 oxidation state. (-2 x 4) + (s) = -2 s = +6
The oxidation number of oxygen in carbon suboxide is -1. In carbon suboxide, C3O2, the carbon atom has an oxidation number of +4, while the two oxygen atoms each have an oxidation number of -1 to give a total charge of zero for the molecule.
The oxidation number for Mn in H2MnO3 is +3. In this compound, oxygen is typically assigned an oxidation number of -2, and hydrogen is +1. By considering the overall charge of the compound and assigning hydrogen and oxygen their usual oxidation states, the oxidation number of Mn can be calculated as +3.

Hydrogen's oxidation number is +1.Chlorin's oxidation number is +1.Oxygen's oxidation number is -2.
The oxidation number of Cr in K2Cr2O7 is +6. This can be determined by assigning the oxidation number of +1 to each K atom, the oxidation number of -2 to each O atom, and applying the rule that the sum of oxidation numbers in a neutral compound is zero.
For an uncombined atom, the oxidation number is 0. It does not give away any electrons. It does not accept electrons from anywhere either.
The oxidation number of acetate (CH3COO-) is -1. The carbon atom has an oxidation number of +3, each hydrogen atom has an oxidation number of +1, and the oxygen atoms have an oxidation number of -2.
In the compound Co2O3 cobalt has an oxidation number of 3 while oxygen has an oxidation number is -2.
The oxidation number of each hydrogen in H2CO2 is +1, while the oxidation number of each carbon in CO2 is +4. This is because hydrogen usually has an oxidation number of +1, and oxygen usually has an oxidation number of -2.
Silicon's oxidation number is +4.Oxygen's oxidation number is -2
