According to the Lewis concept, "when two atoms form a covalent bond between them, each of the atoms attains the stable configuration of the nearest inert gas, by completing its "octet" or 8 electrons in the outermost shell, or " duplet" or 2 electrons in the case of hydrogen."
In other words, the duplet rule states that when an element gets 2 electrons in its valence or last shell it has achieved a stable electronic configuration . The octet rule states that when an element acquires 8 electrons in the valence shell it becomes stable like the noble gases.
Certain elements like lithium and hydrogen do not attain eight electrons in their outermost valence shell.

What do you mean by octet and duplet?
In chemistry, the octet and duplet rules are part of electronic configuration. The octet rule is when the outermost shell has 8 valence electrons. The duplet rule is when the outermost shell has 2 valence electrons, e.g. Helium and Hydrogen.
What is the key difference between the Zaitsev and Hofmann rule in organic chemistry?
The key difference between the Zaitsev and Hofmann rule in organic chemistry is that the Zaitsev rule states that the major product of a reaction is the more substituted alkene, while the Hofmann rule states that the major product is the less substituted alkene.
What does the n stand for in the 4n plus 2 rule of Chemistry?
n is an integer that can be 0,1,2,3,... and so on. All this means is that for an aromatic ring to be aromatic it has to have pi bonds that are 2,6,10,14,18,... and so on. On the other hand a antiaromatic ring will have the formula 4n so that pi bonds are 4,8,12,16,20,... and so on.
What is the duet rule?
OCTET RULE:-The tendency of atoms to require eigth electron configuration in their valence shell, when bonding,is called octet rule.DUPLET RULE:-The tendency of atoms to require two electron configuration in their valence shell, when bonding,is called duplet rule
Why octet rule is not obeyed in the formation of h2 molecule?
hydrogen atoms have only one shell( K-shell) which can accommodate only two electrons. Therefore each hydrogen atom in hydrogen moleculecontributes one electron forming a pair which is shared between the two atoms. Thus in hydrogen molecule duplet rule is followed and not the octet rule.
What do you mean by octet and duplet?
In chemistry, the octet and duplet rules are part of electronic configuration. The octet rule is when the outermost shell has 8 valence electrons. The duplet rule is when the outermost shell has 2 valence electrons, e.g. Helium and Hydrogen.
Do hydrogen attain duplet?
Hydrogen can attain a duplet configuration by bonding with another element to form diatomic molecules like H2. In this form, hydrogen has two electrons, satisfying the duet rule.
What is the octet rule in terms of lewis structures?
Octet rule states that each electron wants to complete its octet ( 8 electrons in the outermost shell) or a duplet (in case of hydrogen and helium).
What is duplet state?
A duplet state is when an element has two electrons in it's outermost shell For example-Helium
What are the rules of chemistry in the society and industry?

What is a zero-sum rule?
a rule that is used to help balance equations (used in chemistry)
Is a duplet electron considered stable?
A duplet electron configuration is considered stable, as it corresponds to having two electrons in the outer energy level, which is the most stable configuration for elements in the first period. Elements like helium achieve a duplet electron configuration and are relatively stable due to their full outermost energy level.
Who is the inorganic chemistry?
Inorganic chemistry study compounds which not contain carbon (several exceptions to this rule exist).
What is the key difference between the Zaitsev and Hofmann rule in organic chemistry?
The key difference between the Zaitsev and Hofmann rule in organic chemistry is that the Zaitsev rule states that the major product of a reaction is the more substituted alkene, while the Hofmann rule states that the major product is the less substituted alkene.

What is a pair of electrons shared between two atoms in a covalent bond?
duplet
What are the characteristics and significance of a duplet in music theory?
A duplet in music theory is a rhythmic grouping of two beats in the space of three. It is significant because it allows for more flexibility in rhythm and can create a sense of tension or syncopation in the music.
