Why does phosphorus and sulfur expand octets in many of their compounds but nitrogen and oxygen never do?

P and S both have 'd' orbitals in outermost shell while N and O do not.

Elements in the third row of the periodic table or lower can have octets?
expanded
What is the electronic geometry of PO4-3?
Total valence electons = 26. Bonding electrons = 6. Place the Phosphorus in the center with the three Oxygens bonded to it. Use 20 (26-6) electrons to fill the octets of the oxygens... you have 2 electons left over to put on the phosphorus to fill its octet. 3 bonds plus 1 lone pair gives a steric number of 4. With one lone pair, the molecular geometry is trigonal pyramidal.
What is the formula for dinitrogen hexafluoride?
It doesn't exist. The valence shell of oxygen (n = 2) does not have access to any d orbitals, so oxygen is unable to expand its octet to produce OF6. However, the compounds sulfur hexafluoride (SF6) and selenium hexafluoride (SF6) do exist because they have access to d orbitals in which they can form expanded octets. The hybridization of the central atom in SF6 and SeF6 is sp3d2.
How many octets of electrons are in a Lewis structure?
The maximum number of electrons in a Lewis structure is eight, which is an octet of electrons.
What is the Lewis dot structure for H H?
The Lewis Dot Structure for Helium (He) is,* He :When Helium wants to bond with another atom, it is one of the three exceptions to the octet rule.*Ex. He:HeWhile most other elements have to bond with octets. Such as Hydrogen, Carbon, and Nitrogen.*H-C_=N:Hydrogen bonds once with Carbon and Nitrogen and Carbon have to make an octet so the three lines (_=) and the same as the dot structure (:::) The two valence electrons on the left side of the Nitrogen atom cannot join the Carbon and Nitrogen bond because there is no way two atoms can have a quadruple bond.Remember that each line equals to two electrons. So Nitrogen and Carbon have 8 electrons that they share, satisfying the octet rule.
What is the maximum and minimum size of a TCP header?
maximum 60 octets minimum 20 octets
What comes in groups in eights?

Why the leading two octets of message digest are stored in PGP message along with the encrypted message digest?
Leading two octets of message digest: L, To enable the recipient to determine if the correct public key (k(A) e ) was used to decrypt the message digest for authentication, by comparing this plaintext copy of the first two octets with the first two octets of the decrypted digest. These octets also serve as a 16-bit frame-check sequence for the message, for authentication and error detection.
Does a Frame relay have a fixed-length frame of fifty-three octets?
In the Telecommunications book on Page 180. The answer is Yes it does have a fixed-length frame of 53 octets.
What is the maximum size of SMS in IS-95?
120 octets
How many octets in ip address?
IPv4 addresses have 4 octets, each octet separated by a period. For example, at this time, one of Yahoo's servers has an ip address of 67.195.160.76.
Because the octets equal to 0 ans 255 are only the numbers 1 through 254 can be used for host information in an IPv4 address?
Because the octets equal to 0 and 255 are reserved
What is a name for groups of eight?
Groups of eight are often called 'octets'.
Elements in the third row of the periodic table or lower can have octets?
