Question

what is an octet of electrons? and which elements contain an octet of electron?

the first right answer gets ten....... i need this now.....

Answer 1

Octet means eight......noble gases (except helium) have 8 electrons in outer energy level

Answer 2

The octet rule is a simple chemical rule of thumb that states that atoms tend to combine in such a way that they each have eight electrons in their valence shells, similar to the electronic configuration of a noble gas. The rule is applied to the main-group elements, especially carbon, nitrogen, oxygen, and the halogens. In simple terms, molecules tend to be more stable when the outer shells of their constituent atoms are empty or full, that is, have 8 electrons in the outer shell.


The octet rule also states that atoms react generally by gaining, losing, or sharing electrons in order to achieve a complete octet of 8 valance electrons. An octet of electrons results in a very stable electron configuration. This stability is the reason that the noble gases are so unreactive. This combination occurs primarily in two ways, electrovalent bonding and covalent bonding.

Answer 3

octet is a group consisting of 8 elements.

Answer 4

octat means having 8 electrons in the outer most orbit that is last orbit.most of the elements contain this,if they dont they try get those needed electrons.

Answer 5

octet means eight, so it is an element wiht eight outer elelectrons, such as the noble gasses; excluding helium
