Almost any metal could have an ON/OS of +1. Those that have a common state of +1 include silver, sodium, potassium, Mercury, lithium, rubidium, caesium, thalium and francium.
Hydrogen has an oxidation number of +1 in most of its compounds and -1 in metal hydrides and hydrocarbons.
Oxidation number of Li is +1. Oxidation number of oxygen is -2.
The rule for hydrogen is that it normally has an oxidation state of +1, EXCEPT in metal hydrides, when it has an oxidation state of -1.Li is a metal, LiH is a metal hydride.Does that tell you what you need to know?
+1 in most of the compounds -1 in metal hydrides
Hydrogen. +1 in most of the compounds -1 in metal hydrides
Hydrogen has an oxidation number of +1 in most of its compounds and -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.
A metal and a nonmetal would form an ionic bond. In an ionic compound, a metal ion would have a positive oxidation number equal to its ionic charge. A nonmetal would have a negative oxidation number equal to its ionic charge.Examples:NaCl oxidation numbers: sodium has an oxidation number of +1, chloride has an oxidation number of -1. So the overall charge of NaCl is zero.CaCl2 oxidation numbers: calcium has an oxidation number of +2, the chloride ion has an oxidation of -1. Since there are two chloride ions, the total negative oxidation number is -2, so CaCl2 has an overall charge of zero.

Hydrogen is a light gas. It generally shows +1 oxidation number.
If Br had an oxidation number of +7, the net charge on the ion would be +1, and not -1. Thus, the oxidation number for Br in BrO3- should be 5+.

The oxidation number of what in K3PO4? In that compound the oxidation number of oxygen is -2, the oxidation number of potassium is +1, and the oxidation number of phosphorus is +5.Realistically, in most compounds you can generally take it as a given that the oxidation number of oxygen is -2 and the oxidation number of any alkali metal is +1. In potassium phosphate, that only leaves the oxidation number of phosphorus to figure out, and since they have to come out to a total of zero ...The oxidation number of a compound is essentially a meaningless phrase.
The assumed oxidation number of nitrogen in ammonia (3+) in this question, is wrongly signed:The correct oxidation number if nitrogen in NITRIDES (like in ammonia NH3, ammonium NH4+ and amino groups -NH2) is minus 3, so hydrogen has oxidation value of plus 1(one, like in H+) which is in fact the only possible form when attached to nonmetals.
