hydrogen
+1 in most of the compounds
-1 in metal hydrides
The halogens (group 17) have an oxidation number of -1, though the halogens below fluorine can have other oxidation numbers as well. Hydrogen can also have an oxidation number of -1 when it forms hydrides.
The oxidation numbers of each element in HNO3 are: H is +1, N is +5, and O is -2. The sum of the oxidation numbers in a neutral compound like HNO3 must equal zero.
This is a compound. Compounds don't have oxidation numbers, only their constituent elements do. If you must have an answer, use 0.
Hydrogen it depends on the other element if it is part of a compound
To find the oxidation number of each element in CH2Cl2, we look at the electronegativity of each element. Carbon typically has an oxidation number of +4, hydrogen +1, and chlorine -1. Hence, the oxidation numbers in CH2Cl2 would be +4 for carbon, +1 for each hydrogen, and -1 for each chlorine.
Cl,Br and Iodine may have oxidation no +1 and -1
Hydrogen. +1 in most of the compounds -1 in metal hydrides and hydrocarbons
Hydrogen has an oxidation number of +1 in most of its compounds and -1 in metal hydrides and hydrocarbons.

Elements with oxidation numbers of +1 include elements in Group 1 of the periodic table, like hydrogen and sodium. Elements with oxidation numbers of -1 include elements in Group 17, like fluorine and chlorine.
In MnCo2, Mn has an oxidation number of +2, and Co has an oxidation number of -1. This is determined by assigning oxidation numbers based on rules for assigning oxidation numbers to each element in the compound.
In H2SO4, the oxidation number of H is +1, the oxidation number of S is +6, and the oxidation number of O is -2. These numbers are determined based on the rules of assigning oxidation numbers in compounds.
