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?
oxidation takes place (rusting)
Where on the periodic table has a positive oxidation number?
Positive oxidation numbers are most common with the metals - groups 1 to 13. However there are many well known compounds where non-metals have positive oxidation numbers- for example NaClO4 where Cl has an oxidation number of +7
Why do nonmetals have a negative oxidation number?
non metals accept electrons. Hence they show a negative oxidation number (negative denotes that the element accepts electrons)
What is the oxidation number for just 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 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

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.
How do non metals react with oxygen?
Oxidation of non-metals (and some metals) is a fire.
Do transitionn metals have a consistent oxidation number?
transition metals have variable oxidation states
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.
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
