Yes, oxygen is an exception to the octet rule. Molecular oxygen can have two unpaired electrons making it a biradical molecule.

NH3 is not an exception to the octet rule. Nitrogen (N) in NH3 has a total of 8 valence electrons (5 from nitrogen and 3 from hydrogen), fulfilling the octet rule. Nitrogen has 3 bonded pairs and 1 lone pair of electrons, following the octet rule.
It is one of many, many exceptions to the octet rule. Hydrogen does NOT require 8 electrons.
It makes two covalent bonds which completes its octet.
Hydrogen is the atom that doesn't always obey the octet rule. It only needs 2 electrons to have a full outer shell, rather than the 8 electrons typically required by the octet rule. Oxygen and bromine usually follow the octet rule.
PF5 obeys the octet rule as it has 5 bonding pairs of electrons around the central phosphorus atom, satisfying the octet. Cs2 does not follow the octet rule as Cs is in Group 1 and can only form ionic bonds. BBr3 is an exception to the octet rule as boron has only 6 electrons around it due to the empty d orbital. CO3 2- also obeys the octet rule as each oxygen atom has a complete octet.
Yes, both Cu+ and Cu2+ violate the octet rule. Copper (Cu) is an exception to the octet rule due to its electron configuration, which allows it to have a partially filled d orbital. This leads to Cu forming compounds where it does not achieve a full octet of electrons.
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, PF5 is an exception to the Lewis octet rule. Phosphorus has 10 electrons around it in PF5, exceeding the octet rule. This is due to the availability of d-orbitals in the valence shell of phosphorus for accommodating extra electrons.

Oxygen can violate the octet rule because it can form stable compounds with less than eight electrons in its valence shell. For example, in molecules like hydrogen peroxide or ozone, oxygen can have six electrons in its valence shell. This is possible due to oxygen's ability to form multiple bonds and accommodate more than eight electrons in its valence shell.
Boron is an exception to the octet rule because it only has six electrons in its outer shell, so it can form stable compounds with fewer than eight electrons. This occurs because boron is in the second row of the periodic table and can form stable compounds by sharing fewer electrons.
