An orbital being full or half full is good (lower in energy - d orbitals) l=0, s orbital (sphere) l=1 p orbital (dumbbell shape) l=2 d orbital (2 p orbitals together, x shape) l=3 f orbital l=4 g orbital n=1, l=0 is called 1s n=2, l=0 is called 2s n=2, l=1 is called 2p n=3, l=2 is called 3d 1s^2 means 2 electrons are in the 1s orbital 3d^7 means 7 electrons are in the 3d orbital

The octet rule dictates that atoms are most stable when their valence shells are filled with eight electrons. It is based on the observation that the atoms of the main group elements have a tendency to participate in chemical bonding in such a way that each atom of the resulting molecule has eight electrons in the valence shell. The octet rule is o...
A few examples detailing the chemical bonding of atoms in compliance with the octet rule can be found in this subsection.
Not all elements and compounds follow the octet rule. Some of the exceptions to this rule are listed below. 1. An ion, atom, or a molecule containing an unpaired valence electron is called a free radical. These species disobey the octet rule. However, they are very unstable and tend to spontaneously dimerize. 2. Since the first shell can only accom...
How is the Octet Rule Useful?
The chemical behaviour of the main group elements can be predicted with the help of the octet rule. This is because the rule only involves ‘s’ and ‘p’ electrons, where the octet corresponds to an electron configuration ending with s2p6. These elements tend to form bonds in order to obtain stable obtain octet configurations.
Do the Oxygen Atoms in O2 Molecules Have Octet Configurations?
Yes, each oxygen atom in the O2molecule is surrounded by a total of 8 valence electrons. Oxygen has a total of 6 electrons in the valence shell. In order to obtain a stable octet, the two oxygen atoms share a total of four electrons via a double bond.
List Four Elements that do not Obey the Octet Rule
Since ‘1p’ subshells do not exist, some elements find stability in 1s2configurations. On the other hand, some elements exhibit hypervalency and have the ability to form hypervalent molecules. Some elements that disobey the octet rule include: 1. Hydrogen 2. Lithium 3. Phosphorus 4. Sulfur Thus, a brief explanation of the octet rule is provided in this article along with its exceptions. To learn more about concepts related to chemical bonding, such as hybridization, register with BYJU’S and do...
Use the remaining electrons on the outer atoms to satisfy the octet rule 4. Place any remaining electrons in lone pairs around the central atom 5. If the central atom does not satisfy the octet, use lone electrons from the outer atoms to form additional bonds between the center and outer atoms.
UNIT 1 ANSWERS. CHAPTER 1. a melting. subliming/sublimation. freezing. subliming/sublimation. a. solid liquid gas. Note: Solids should have regularly packed particles touching. Liquids should have most of the particles touching at least some of their neighbours, but with gaps here and there, and no regularity.
