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 types of atoms undergo covalent bonding?
They are the atoms that want to obtain a complete shell either duplet or octet.
What is the condition for covalent bond formation?
the condition for covalent bond is that both has to be non metal so that they can share their valence electrons to form duplet or octet configuration
How many electrons must neon loose to form a anion?
Do note that elements form anions to gain stability (duplet and octet rules). Neon is a noble gas. It is inert, as its valence shell is full (and follows the octet rule). It does not need to form an anion, as it is already stable.
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 duplet rule in chemistry?
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 is a atom that forms a stable ion but not have an octet structure?
Helium; it has a duplet structure.
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
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.
