Oxidation numbers of hydrogen

The oxidation number of hydrogen is taken to be +1 (except in H2, which is the elementary state). [Pg.219]

The oxidation number of hydrogen is +1 in combination with nonmetals and —1 in combination with metals. [Pg.104]

KH hi most cases hydrogen has an oxidation number of+1. hi compounds with metals, however, the metal has a positive oxidation number and the oxidation number of hydrogen is -1. This requires potassium to be +1. [Pg.1357]

The oxidation number of hydrogen in compounds is +1 except when the hydrogen is combined with active metals then it is -1. [Pg.213]

Determine the oxidation number of sulfur in sulfuric acid, H2SC>4. The sum of all the oxidation numbers must equal zero, since this is a neutral compound. The oxidation numbers of hydrogen (+1) and oxygen (-2) are known, so the oxidation number of sulfur can be determined ... [Pg.53]

The oxidation number of hydrogen is -i-l on both sides of the equation, so hydrogen is neither oxidized nor reduced. [Pg.479]

Oxidation number of hydrogen in compounds is generally +1 except in metallic hydrides wherein its oxidation number... [Pg.18]

Here, oxidation number of hydrogen changes from 0 (in H2) to +1 (in H20). It is, therefore, a case of oxidation of hydrogen. [Pg.19]

The oxidation number of hydrogen in its compounds is equal to +1, except in its binary compounds with an alkali metal, an alkaline earth metal, or aluminum, when it is -1. (The ion is named the hydride ion.)... [Pg.446]

Find the oxidation number of hydrogen in each of the following compounds ... [Pg.460]

What are the maximum and minimum oxidation numbers of hydrogen ... [Pg.461]

The minimum oxidation number of hydrogen is -1. That of any other nonmetallic atom is equal to its group number minus 8. That of any metallic atom is 0. [Pg.204]

The oxidation number of copper increases from 0 to +2 as it is oxidized in the reaction. The oxidation number of nitrogen decreases from +5 to +4 as it is reduced in the formation of NO2. The oxidation numbers of hydrogen and oxygen do not change. Note that the nitrogen atoms remain unchanged in the nitrate ion (N03 ), which appears on both sides of the equation. It is neither oxidized nor reduced. [Pg.645]

Hydrogen is assigned oxidation number +1 in its compounds, except in metal hydrides such as LiH, where convention 2 takes precedence and the oxidation number of hydrogen is —1. [Pg.98]

The oxidation number of hydrogen is +1, except when it is bonded to metals in binary compounds. In these cases (for example, LiH, NaH, CaH2>, its oxidation number is 1. [Pg.123]

The oxidation number of hydrogen is +1 when it is combined with a more electronegative element. The oxidation number of hydrogen is +1 in the CH4, NH3, H2O, and HCl molecules. [Pg.286]

The oxidation number of hydrogen drops from 0 to -1 in this reaction. [Pg.710]

The oxidation number of hydrogen is usually + 1 (except in hydrides, where hydrogen ions bond to metal ions and have an oxidation number of -1). [Pg.203]

The oxidation number of hydrogen is +1 in all of its compounds (except those with metals, where it is -1, and in the elementary and self-binding forms of hydrogen, where it is zero). [Pg.106]
