It forms a divalent cation, Ca2+, by losing two electrons and attains the electronic configuration of [Ar].
because it does
When sodium loses its single valence electron, it achieves the noble gas configuration of neon, which is an octet.
more than sure that whole group is covalent bonding such as Iodine is written I2 or Bromine is Br2. Fluorine is also in this, example F2, the 2 outer electrons as each is 19, 2,8,8,1 is shared between the 2 atoms.
yes PCl3 obey octet rule there are 5 electrons in the valence shell of phosphorous it need 3 electron to complete its octet so it form bond with 3 chlorine after bond formation there are 8 electron in its octet it obey 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).
Yes
Neon obeys the octet rule by not reacting and not forming ionic compounds as it already has a stable outer shell of eight electrons.

BF3 and other Lewis acids. Also BrF5 and other inter-halogen compounds.
No chlorine oxides will obey the octet rule.
No, Transition metals do not obey the octet rule in simple compounds , Am is an 'f' block transition metal.
Hydrogen does not obey the octet rule. Boron does not always obey the octet rule and in fact forms Lewis acids such as BF3 which only has 6 electrons.

No. Some molecules, such as boron triflouride (BF3) and phosphorus pendachloride (PCl5) are octect violators.
no it does not follow octet rule
yes PCl3 obey octet rule there are 5 electrons in the valence shell of phosphorous it need 3 electron to complete its octet so it form bond with 3 chlorine after bond formation there are 8 electron in its octet it obey octet rule
