Chlorine Cl : it can have a higher valence (ClO2, HClO3) than predicted by the octet rule.
Hydrogen H and oxygen O cannot escape the octet rule.
Atoms in the third period or beyond (period 3 and below) can exceed the octet rule due to the availability of d orbitals for expanded valence shells. Examples include sulfur, phosphorus, chlorine, and others in the third row and beyond in the periodic table. Additionally, atoms with an odd number of valence electrons, such as nitrogen and radicals, may also not follow the octet rule.
No chlorine oxides will obey the octet rule.
no it does not follow octet rule
Cs2, NO3, and PO43 do not obey the octet rule because they have an odd number of valence electrons. CI4 and SCI4 do not obey the octet rule because the central atom (Cl or S) exceeds the octet by having more than eight valence electrons.
The elements can be described by dot structure. Metals combine with other elements to make its octet complete.

No chlorine oxides will obey the octet rule.
Yes. Both O-F bonds are single covalent, so all three atoms can claim 8 electrons.
The oxygen atoms in the ion do obey the octet rule. The phosphorus atom has more than eight electrons in its valence shell. It is because of the existence of vacant 3d orbitals.
no it does not follow octet rule
No, SF6 doesn't. If you draw out the Lewis structure, all 6 fluorine atoms have to connect to the sulfur.
Covalent compounds obey the octet rule by sharing electrons between atoms in order to achieve a full outer shell of electrons, usually 8 electrons. This sharing allows each atom to achieve greater stability by filling its valence shell with the desired number of electrons.
Cs2, NO3, and PO43 do not obey the octet rule because they have an odd number of valence electrons. CI4 and SCI4 do not obey the octet rule because the central atom (Cl or S) exceeds the octet by having more than eight valence electrons.
The bolded statements are true:1. The octet rule can be violated. 2. Atoms are most stable when their atomic number is divisible by 8.3. All free atoms contribute eight valence electrons to form molecules.4. Only the oxygen atom can have an expandable octet.5. In order to obey the octet rule, some atoms have to share more than one pair of electrons.
BCl3 and BEH2 obey the octet rule because Boron and Beryllium are exceptions to the octet rule and can have stable electron configurations with less than 8 electrons. Cl3CF, NO, and SbF5 do not obey the octet rule because they have incomplete or expanded valence shells.
#In covalent bondig electrons are shared by atoms. A bond is made up of two shared electrons of opposite spin.Many molecules contain atoms that obey the octet rule where the y share enough electrons to acheive an octet. Hydrogen is different it follows the duet rule, just shares two electrons. (achieving the octet or duet means that an atom has a similar electronic configuration to a noble gas)
