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


The oxidation number is the blank to comply with the octet rule?

The oxidant number is the number of electrons gained or lost by an atom to comply with the octet rule


What is the likely common oxidation number of iodine?

As it forms the I- ion froming an octet its most likely oxidation number is -1


What is the oxidation number of neon?

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.


Which part of an atom helps describe the property of the atom and determines what kind of element it is?

Protons (the number of ..) determine the 'kind' of element,and the electrons in the outmost valency orbital determine the properties(the number of electron; and 'octet' rule: "make it eight preferably').


What rule is used to determine how many covalent bonds an element can form?

The number of Covalent Bonds is equal to eight minus the group number.


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 for 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 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.


Why do elements in group 17 have an oxidation number of -1?

Because they require one electron to complete their octet


What is the maximum number of electrons that a representative element can possess?

8 so then it is an Octet.


What was your clue for knowing the number of lines in an octet?

The clue for knowing the number of lines in an octet is that in a Lewis structure a line represents two electrons. This means that an element with four lines attached to other elements has an octet.
