moloecules that do not follow the octet rule will seek to have more than a full octet.
The reason why some of these compounds exhibit paramagnitisim is due to the intrinsic nature of paramagnatisim.
Substances that have one unpaired electron are paramagnetic and those with no unpaired electrons are diamagnetic.
So a substance with 9 electrons is likely to be paramagnetic and those with even numbers are likely to be diamagnetic.
To tell if a compound is dia or para magnetic it is advisable to draw its structure and count the electrons and then place the electrons into a crystal field stabilisation enetgy diagram(C.F.S.E.) following the rules for the ligands(high/low spin, separation energy, spectrochemical series) this will give you the C.F.S.E. in bhor magnatons and if the molecule is diamagnetic or paramagnetic.
What else can I help you with?
Does the compound P2F4 exhibit an expanded octet?
Yes, the compound P2F4 does exhibit an expanded octet.
Two elements that form compounds that can be exceptions to the octet rule?
Boron and fluorine in the trivalent boron compound BF3 have only 6 electrons in the valence shell.Oxygen and nitrogen in nitric oxide, NO, contain one or more atoms which have an odd number (one UNpaired '.' ) of electrons. Lewis dot structure |N.=O
Which molecule obeys the octet rule cl3cf bcl3 no sbf5 beh2?
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.
Which of the following elements are capable of forming molecules in which an atom has an expanded octet C P B O Se?
The elements in period 3 and above have d orbitals available for bonding which makes the "expansion" of the octet more likely. period 2 elements do not, the 2d shell has only s and p orbitals. P is in period 3, an example is PCl5 with 5 electron pairs. Se in period 4 can also expand its octet, an example is SeF6, with 6 electron pairs.
What molecules do not violate the octet rule?
I think two elements that does not follow the octet rule are boron and beryllium. These elements always have one electron pair less than normal configuration. Boron is an important element for our body.
Does the compound P2F4 exhibit an expanded octet?
Yes, the compound P2F4 does exhibit an expanded octet.
What are some exceptions to the octet rule?
No but apples do!
Is water an exception to the octet rule?
It is one of many, many exceptions to the octet rule. Hydrogen does NOT require 8 electrons.

Do you always follow the octet rule when drawing a Lewis structure?
No, the octet rule is a guideline, but there are exceptions for certain molecules and ions where atoms may have more or fewer than eight electrons in their valence shell. These exceptions typically involve elements from period 3 and below and can include expanded octets, odd-electron species, and species with incomplete octets.
Which three elements violate the octet rule?
The octet rule cannot be satisfied in molecules whose total number of valence electrons is an odd number.There are also molecules in which an atom has fewer, or more, than an octet of valence electrons.
Which molecule obeys the octet rule cl3cf bcl3 no sbf5 beh2?
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.

Another word for an 8 piece band?
its called an octet
What is an exception to the octet rule?
Yes. Hydrogen follows the duet rule, and boron and a few other elements are exceptions. Also, the noble gases can have expanded valence levels with more than eight electrons, though they only bond under certain conditions.
