Flourins has 2s2 and 2p5 configuration and total 9 electrons in outermost shell. There are two possibilities for fluorine i.e. either to complete the outermost shell or to follow the octet rule. If it follow the octet rule there will remain 4 electrons in 2p. Hence its reactivity towards metals or other compounds will differ which is against its nature.Thats why flourine shows restrictions towards octet rule

Why fluorine exist as a diatomic molecule?
Each fluorine atom has 7 electrons in its outer shell, but a setup of 8 outer shell electrons (called an octet) is stable. To get this octet a fluorine atom will form a single covalent bond with another fluorine atom. Each atom give one electron to be shared between the two.
Is NF4 a possible compound of nitrogen and fluorine?
No. Nitrogen is trivalent as this achieves the octet. heavier members of group 15 are trivalent and pentavalent.
Which halogen is most likely to react?
it will mostly likely react with noble gases, because they only require one additional electron to form a full octet.
What element has the greatest electronegativity?
Fluorine... by far. Its so electronegative that it will never form double bonds, even if they would make sense by the octet rule. BF3 is a really good example of this
When a fluorine atom has seven electrons in its outer shell is it an ion with a plus or minus charge?
A fluorine atom that has seven electrons in its outer shell would be neutral. A negatively charged fluoride ion, Fl-, forms when a fluorine atom gains one electron so that it has an octet, or a noble gas configuration of electrons.
What does a fluorine atom need?
Fluorine need one electron. It needs one electron to complete its octet.
How many electrons does fluorine need to satisfy the octet rule?
One
How many more electrons does Fluorine need to have a stable octet?
1
What number of covalent bonds will fluorine form in order to achieve an octet?
One.

Which among nitrogen oxygen and fluorine is most reactive?
Among these elements, fluorine is more reactive. It easily gains one electron to complete its octet.
How many valence electrons are transferred from the calcium atom to iodine in the formatoin of the compound calcium iodide?
during the formation of calcium iodide,calcium donates two of its +ve ions each to a fluorine atom(2 in number) thereby making its octet and also fulfills the octet formation of each of fluorine atom..
Is PF5 an exception to the Lewis octet rule?
P certainly obeys the octet rule in phosphides: PH3, Na3P etc.
Is NF4 a possible compound of nitrogen and fluorine?
No. Nitrogen is trivalent as this achieves the octet. heavier members of group 15 are trivalent and pentavalent.
Does BeF2 obey the octet rule?
No it is not fully obeying the octet rule. Boron has only 6 electrons (3 own + 3 from each F atom), lacking two for the octet. Fluorine is 3x satisfied, each with 8 electrons (each has 7 own plus 1 from boron).
Which halogen is most likely to react?
it will mostly likely react with noble gases, because they only require one additional electron to form a full octet.
What elements are stable Neon carbon boron or fluorine?
neon obeys octet rule (it has 8 electrons in its outer most shell) and is thus stable.
