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 rule of sodium sulfate in forensic chemistry?
Na2SO4
Why you should not stir the mixture that is in the filter funnel in chemistry?
This is not a rule in laboratory.
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 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

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).
Is a duplet electron considered stable?
yes as a duplet electron has to electrons in its outtermost shell.:)
What is duplet state?
A duplet state is when an element has two electrons in it's outermost shell For example-Helium
Do hydrogen attain duplet?
Yes
What are the rules of chemistry in the society and industry?
Give the rule of chemistry in society and industry
Can a person with BSC.ED in chemistry do MSC in chemistry?
Depends on the university, but as a general rule -YES
What is the rule of shelter in chemistry?
to have a rest and to be comfortable
How could oxygen achieve a stable octet?
Yes. The octet rule is a rule of thumb that states that atoms tend for form bonds that allow the bonded atoms to have eight electrons in their valence shells. This is a "driving force" in chemistry, and it explains many, many reactions. Use the link below to gather more information.
What is a zero-sum rule?
a rule that is used to help balance equations (used in chemistry)
What is the rule of sodium sulfate in forensic chemistry?
Na2SO4
Who is the inorganic chemistry?
Inorganic chemistry study compounds which not contain carbon (several exceptions to this rule exist).
