No.
Some molecules, such as boron triflouride (BF3) and phosphorus pendachloride (PCl5) are octect violators.
Formaldehyde does.
Carbon forms a double bond with oxygen and single bonds with two hydrogens.
Yes. Si (silicon) usually obeys the octet rule.
The atoms in the compound share electrons to form covalent (molecular) bonds and thus obey the octet rule.
Yes both of carbon and oxygen obey the octet rule in CO2
no
NOPE
Yes.
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.
The element silicon would be expected to form 4 covalent bond(s) in order to obey the octet rule. Si is a nonmetal in group 4A, and therefore has 4 valence electrons. In order to obey the octet rule, it needs to gain 4 electrons. It can do this by forming 4 single covalent bonds.
The element Arsenic would be expected to form 3 covalent bonds in order to obey the octet rule. As is a nonmetal in group 5A, and therefore has 5 valence electrons. In order to obey the octet rule, it needs to gain 3electrons. It can do this by forming 3 single covalent bonds.
I know for sure BBr# & PF5 do not obey the octet rule, but i can't remember the rule of isotopes so I can't say for sure whether or not CO3 -2 obeys it or not.
Yes
because it does
Neon obeys the octet rule by not reacting and not forming ionic compounds as it already has a stable outer shell of eight electrons.
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.
Covalent.
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 it does not follow octet rule
BF3 and other Lewis acids. Also BrF5 and other inter-halogen compounds.
The element tellurium would be expected to form 2covalent bonds in order to obey the octet rule.Te is a nonmetal in group 6A, and therefore has 6 valence electrons. In order to obey the octet rule, it needs to gain 2 electrons. It can do this by forming 2single covalent bonds.
Yes. Both O-F bonds are single covalent, so all three atoms can claim 8 electrons.
