three exceptions to the octet rule

Exceptions to the Octet Rule - While the octet rule is very useful for describing bonding in a large number of compounds, there are many exceptions to this rule..

Where duplet is formed? A hydrogen atom has only one electron in its valence shell. It needs one more electron to fill its valence shell. The completed shell has the electronic arrangement of the noble gas helium, yet an octet is not completed. However we still get a stable m..

The above configurations show that the electronic configurations of chromium and copper are slightly different from that of other elements. The electronic configurations for these atoms are expected to be: Cr: [Ar]3d 4 4s 2 and Cu: [Ar] 3d 9 4s 2 However, the actual configuratio..

>The outermost shell of an atom cannot accommodate more than 8 electrons, even if it has a capacity to accommodate more electrons. This is a very important rule and is also called the Octet rule. The presence of 8 electrons in the outermost shell makes the atom very st..
