oxidation numbers

[KaylynnPierce2I]

As said in lecture, "metals form cations with different oxidation number," what are oxidation numbers?

[JacksonWissing2G]

Oxidation numbers are what the charge of an atom in a compound would be, if you separated that atom from the rest. The oxidation number for Na in NaCl for example would be +1.

[Aryan Singh 3F]

Oxidation numbers refers to the cation charge of the specific metal. For example, scandium has an oxidation state of +3, whereas nickel has an oxidation state of +2.

[Nithya Narapa Reddy]

oxidation numbers refer to the total number of electrons that an element either gains or loses. A positive oxidation number means it loses electrons and vice versa.

[Hailey Jeon]

Oxidation number is the number of electrons gained or lost after the oxidation reaction has occurred. Positive means that the element is more positive due to the lose of electrons; negative means that the element is more negative due to the gain of electrons.

[Alice Guey 1B]

Oxidation numbers are most commonly used when analyzing oxidation-reduction reactions. While breaking and forming bonds to make new molecules, atoms may lose or gain electrons. The number of electrons lost or gained is the oxidation number.

Oxidation numbers are the electrons that an atom either gains or loses in order to form a chemical bond with another atom during an oxidation reaction. It can also be described as the charge that the atom would have if the compound was made up of ions. Hope that helps!
