Question

What is an example of the Octet rule?

Can someone please give me an example ?

Answer 1

timaa, waht grade r u in girl? o-o

Answer 2

CHEMISTRY, IM IN 10TH AND 11TH.

Answer 3

WHY ?

Answer 4

IHTS NO WONDER I DONT UNDERSTAND DIS PEACHES o-o

Answer 5

I thought I was goin peaches :D

Answer 6

what is the octet rule i forgot.. I know it if u tell me what it is

Answer 7

LOL , I NEED HELP SO BAD I HAVE 4 more QUESTIONS LIKE THIS! and have only 5 mins left D;

Answer 8

here ya go timaa http://kgortney.pbworks.com/f/octet_rule.gif

Answer 9

what is the rule?

Answer 10

The Octet Rule says that atoms will usually gain, lose, or share electrons in order to have a total of 8 electrons in their outer shell. An exception to this rule are free radicals

Answer 11

soo iron?

Answer 12

basically anything but H and He

Answer 14

Char not a website, my teachers will find out lol

Answer 15

sorry timaa ;-;

Answer 16

The octet rule states that all atoms in a lewis structure must fill their octets by having 8 electrons around them. Some atoms can break this rule by having more than 8 electrons, one example is Oxygen. o-o

Answer 17

;-; i told ya what it was lol

Answer 18

The octet rule is a simple rule that defines maximum no. of valence electrons around atoms and is used extensively for determining Lewis structures. The octet rule is actually quite a lousy rule that works consistently only for C,N,O and F (and H using 2 electrons instead of 8)
For other elements, like S, P etc, they can have expanded valence shells or electron deficient shells (like Be) which don't obey the octet rule.

Let's give an example.
Draw the Lewis structure of water (H2O)
First we identify how many valence electrons we have - this will be (1x2 + 6) = 8 valence electrons.
Now we draw it H - O - H. This implies two bonds (so four electrons in bonding), leaving 2 lone pairs. Where do they go? Well octet rule tells us it is optimal for O to have a total of 8 valence electrons around it. It already has 4 from the 2 bonding pairs, so we add 2 lone pairs to O to make 8.

What about CO2?
Begin with valence electrons: (4+2x6) = 16 valence electrons
Let's start with O - C - O.
This expends 2 pairs of electrons for bonding (4), so we have 12 e's left to place. We can put 6 on both O's to use them up completing the octet rule for O's but that means C has only 4 electrons, violating the octet rule.

Let's try O=C - O. This uses immediately 6 electrons, due to the extra double bond. We have 10 e's left to place. We can try putting 4e's on the double bonded O, and 6 e's on the single bonded O, but the C is left with only 6 valence electrons.
So try O=C=O. This uses up 8 bonding electrons leaving 8 left...which we can split into 2 lots of 4 for each O, and voila, all atoms have 8 valence electrons.
This is the basis of the octet rule. ^_^ yahoOOOOOOOOOO
