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.

What are the oxidation numbers for the metal groups 1A 2A 3A?
Group 1 or alkali metals (+1 oxidation number). Group 2 or alkaline earth metals (+2 oxidation number).
How do oxidation numbers determine if an element is a metal or a nonmetal?
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.
What do metals do when they combine with non metals like oxygen?
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.
What is the oxidation numbers of alkaline metals?
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
What is the oxidation number of NaH?
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.
What is the oxidation number for sulfur?
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.
What is Sulphur's oxidation number?
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.
Which non-metals show only one oxidation number when they form compounds?
oxygen and fluorine
What are the oxidation numbers for the metal groups 1A 2A 3A?
Group 1 or alkali metals (+1 oxidation number). Group 2 or alkaline earth metals (+2 oxidation number).
What is the oxidation number of hydrogeon when it is combined with a metal?
Hydrogen is a non metal. Metals are electropositive than hydrogen. Therefore, hydrogen atoms in metal hydrides have oxidation number -1.
Do transitionn metals have a consistent oxidation number?
transition metals have variable oxidation states
How do oxidation numbers determine if an element is a metal or a nonmetal?
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.

What is the oxidation number of NaH?
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.
Do all metals have a number in parentheses?
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.
What is the oxidation number of Re?
The oxidation number of rhenium (Re) can vary, but it is most commonly found in the +7 oxidation state.
