The octet rule states that atoms tend to gain, lose, or share electrons to achieve a full outer shell of eight electrons. By following this rule, you can determine the oxidation number of an element based on how many electrons it gains or loses in order to reach a full octet. The oxidation number corresponds to the charge an atom would have if the compound were ionic.

What does the oxidation number tell about an ionic bond?
The oxidation number of an element in an ionic bond indicates its charge when it gains or loses electrons to achieve a stable octet. By comparing the oxidation numbers of the elements involved, you can determine how many electrons each element has gained or lost in the formation of the bond.
What is the maximum oxidation number of magnesium?
The oxidation number of magnesium is +2. Any other for this element would be energetically unfavorable and unstable.
What determines the most likely oxidation state of element?
The most likely oxidation state of an element is determined by the number of valence electrons it has. Elements tend to react in a way that allows them to achieve a full outer electron shell, often following the octet rule. This leads to the most common oxidation state for that element.
Why is fluorine's oxidation number always negative?
Fluorine is the most electronegative element, meaning it has a strong tendency to gain electrons in chemical reactions. This leads to a stable octet configuration, resulting in a negative oxidation number (-1) when forming compounds.
What is the Oxidation number of MgCl2?
The oxidation number of Mg in MgCl2 is +2, and the oxidation number of Cl is -1. Magnesium typically forms ionic compounds where it loses two electrons to achieve a stable octet configuration, resulting in a +2 oxidation state. Chlorine gains one electron to achieve a stable octet, resulting in a -1 oxidation state.
What does the oxidation number tell about an ionic bond?

What is the oxidation number of element number nine?
-1. Fluorine has an atomic number of 9. It has seven valence electrons (in the 2d shell) so it gains one electron to achieve th octet- hence it has an oxidation number of -1

What determines the most likely oxidation state of an element?
the number of electrons the element needs to lose or gain to have a full valence shell
Does oxygen ever have a 3- oxidation number?
No, oxygen will never have a -3 oxidation number. If it had a -3 oxidation number, it would not have a full octet. It would have a +1 charge, therefore making it not happy.
What is the oxidation number Ne?
The oxidation number of Neon is 0. It does not want to gain or lose any electrons. It already has a full octet, therefore it remains at 0.
What is the Oxidation number of MgCl2?
The oxidation number of Mg in MgCl2 is +2, and the oxidation number of Cl is -1. Magnesium typically forms ionic compounds where it loses two electrons to achieve a stable octet configuration, resulting in a +2 oxidation state. Chlorine gains one electron to achieve a stable octet, resulting in a -1 oxidation state.
What rule is used to determine how many covalent bonds an element can form?
The octet rule is used to determine how many covalent bonds an element can form. This rule states that elements tend to gain, lose, or share electrons to achieve a full outer valence shell with eight electrons.
What is the oxidation number sodium chloride?
The oxidation number of sodium in sodium chloride (NaCl) is +1, and the oxidation number of chloride is -1. Sodium tends to lose one electron to achieve a stable octet, giving it a +1 oxidation state, while chloride tends to gain one electron to achieve a stable octet, resulting in a -1 oxidation state.
What is an oxidation number example?
An example of an oxidation number is in the molecule HCl, where hydrogen has an oxidation number of +1 and chlorine has an oxidation number of -1. The sum of the oxidation numbers in a neutral compound is always zero.
