Does a metal or nonmetal have both positive and negative oxidation numbers?

A metal typically has only positive oxidation numbers, while a nonmetal can have both positive and negative oxidation numbers. Metals tend to lose electrons (positive oxidation numbers) to form cations, while nonmetals can gain or lose electrons to form a variety of oxidation states.


Can metals have positive and negative oxidation numbers?

Yes, metals can have positive oxidation numbers when they lose electrons to form cations. However, metals typically do not have negative oxidation numbers since they usually do not gain electrons to form anions.


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 non metals?

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 can have both positive and negative oxidation numbers?

Molecules with transition metals like manganese, iron, or copper can have both positive and negative oxidation numbers. The oxidation number depends on the specific chemical environment and the oxidation state of the metal ion.


Is a property that can have both positive and negative oxidation numbers a metal or nonmetal?

A property that can have both positive and negative oxidation numbers typically corresponds to a metal. Metals tend to lose electrons to form positive oxidation states and gain electrons to form negative oxidation states, while nonmetals typically gain electrons to form negative oxidation states.


Do nonmetals have positive and negative oxidation numbers?

Nonmetals typically have negative oxidation numbers, as they tend to gain electrons in chemical reactions. However, in certain compounds or instances, nonmetals can also have positive oxidation numbers if they lose electrons.


What is an oxidation number and how does an atom get one?

Before involving any chemical reactions or bonds, an atom has an oxidation number of zero. Accepting electrons will lower the oxidation number to negative numbers. Discharging electrons such as metals will result in positive oxidation numbers.


Are electron affinity values usually positive or negative numbers?

Positive for nonmetals and negative for metals


Do all metals have two oxidation numbers?

No, not all metals have two oxidation numbers. Some metals may have multiple oxidation numbers depending on the bonding situation and the compounds they form.


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.


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
