The oxidation number of non-metals can vary depending on the element and the compound it is in. Generally, non-metals tend to have negative oxidation numbers when they form compounds with metals, but they can also have positive oxidation numbers when they form compounds with other non-metals.
Group 1 or alkali metals (+1 oxidation number). Group 2 or alkaline earth metals (+2 oxidation number).
Generally, metals attain positive oxidation numbers only. Non metals can have either positive or negative oxidation states. If an oxidation number is a negative value, it can be deduced that it's a non metal element.
Metals tend to lose electrons when they combine with non-metals like oxygen, forming positive ions. These positive ions then combine with the negative ions of non-metals like oxygen to form compounds, such as metal oxides.
The question should be either 'alkali metals' or 'alkaline earth metals'. For alkali metals or group 1 elements, the oxidation number is +1 (note. hyddrogen can have +1 and -1). For alkaline earth metals, the oxidation number is +2 In addition all these elements will have an oxidation number of 0 in their elemental form
The oxidation number of Na in NaH is +1 because alkali metals like Na typically have a +1 oxidation state in compounds. The oxidation number of H in NaH is -1 because hydrogen usually has a -1 oxidation state when bonded to metals.
The oxidation number in atomic sulfur is 0. With other non metals, it produces many ions where its oxidation number varies from -2 to +6. The oxidation number of sulfide ion (which is produced usually with ions from metals) is -2.
The oxidation number in atomic sulfur is 0. The oxidation number of sulfide ion is -2. With oxygen and other non metals, it makes numerous ions where its oxidation number varies from -2 to +6.
oxygen and fluorine
Group 1 or alkali metals (+1 oxidation number). Group 2 or alkaline earth metals (+2 oxidation number).
Hydrogen is a non metal. Metals are electropositive than hydrogen. Therefore, hydrogen atoms in metal hydrides have oxidation number -1.
transition metals have variable oxidation states
Generally, metals attain positive oxidation numbers only. Non metals can have either positive or negative oxidation states. If an oxidation number is a negative value, it can be deduced that it's a non metal element.

The oxidation number of Na in NaH is +1 because alkali metals like Na typically have a +1 oxidation state in compounds. The oxidation number of H in NaH is -1 because hydrogen usually has a -1 oxidation state when bonded to metals.
Not all metals have a number in parentheses. The number in parentheses typically indicates the oxidation state of the metal in a compound, which is relevant for transition metals that can exhibit multiple oxidation states. However, many metals, especially those in groups like alkali and alkaline earth metals, commonly have a fixed oxidation state and may not require such notation.
The oxidation number of rhenium (Re) can vary, but it is most commonly found in the +7 oxidation state.
