Definition Of The Octet Rule
Definition Of The Octet Rule. Biology glossary search by everythingbio.com atoms will lose, gain or share electrons to achieve the electron configuration of the nearest noble gas (8 valence electrons except for he with 2). The rule is especially applicable to carbon, nitrogen, oxygen, and the halogens, but also to metals such as sodium or magnesium.
(chemistry) the statement that when atoms combine to form molecules they generally each lose, gain, or share valence ele. It defines the propensity of elements belonging to the main groups in the periodic table, to react with each other to form compounds and become stable. The octet rule reflects the observation that the most stable ions of many elements have eight electrons in their valence shell for gaining the best possible stability.

It also determines whether electrons are added or lost through. It helps us understand that an atom is most stable when it has valence shells filled with 8 electrons. This gives the atom a valence shell resembling that of a noble gas.
It Defines The Propensity Of Elements Belonging To The Main Groups In The Periodic Table, To React With Each Other To Form Compounds And Become Stable.
The rule is especially applicable to carbon, nitrogen, oxygen, and the halogens, but also to metals such as sodium or magnesium. The octet rule reflects the observation that the most stable ions of many elements have eight electrons in their valence shell for gaining the best possible stability. Octet rule is called ‘the chemical rule of thumb’.
A Valence Shell Is The Outer Shell Of An Atom.
The octet rule is a general rule of thumb that applies to most atoms. The octet rule was postulated by gilbert newton lewis. The octet rule or octet rule is a postulate that is used in the context of the chemistry.

The octet rule helps us predict the chemical behaviour of the elements. The octet rule is a chemical rule of thumb that states that atoms of low (<20) atomic number tend to combine in such a way that they each have eight electrons in their valence shells, giving them the same electronic configuration as a noble gas. Thus, to obtain a stable octet configuration, the elements tend to form bonds.
Eight Electrons In The Outer Shell Allows Atoms To Have A Configuration That Is Similar To The Closest Noble Gas.
It explains the reason for chemical combinations of atoms by ionic or covalent bonds. The octet rule explains that atoms combine either by transfer of valence electrons from one atom to another (gaining or losing) or by sharing of valence electrons in order to have an octet i.e., eight electrons in their valence shells. The octet rule is a general rule used by chemists to predict the possible bonds formed by main group elements, especially carbon, nitrogen, oxygen, the.
