What is meant by octet configuration?

Octet configuration is a state of attaining 8 electrons in the outermost shell or valence shell of an atom.

What is octet configuration class 10?

In octet configuration, the atom has 8 electrons in its outermost orbit.

How do I find my octet configuration?

Referring to the octet rule, atoms attempt to get a noble gas electron configuration, which is eight valence electrons. Sodium has one valence electron, so giving it up would result in the same electron configuration as neon. Chlorine has seven valence electrons, so if it takes one it will have eight (an octet).

What are the examples of octet rule?

Octet Rule Example: Sodium Chloride The second is a nonmetal which has high electronegativity. A good example of this can be chlorine. A chlorine atom in its outer electron shell has seven electrons. Here, the first and second shells have two and eight electrons respectively.

What is octet Class 9?

Octet means the presence of 8 electrons in the outermost shell of an atom which means atom is stable and has the electron arrangement of inert gas. Every atom wants to attain stability so they combine with one another and by gaining or losing or mutually sharing electrons they reach the octet state.

What is octet and duet rule?

The rule of duet refers to the first five elements of the periodic table. They are most stable when the 1s orbital is filled with two (duet) electrons. The rule of octet refers to the filling of the s and p orbital with eight (octet) electrons in order to become stable like a noble gas s2p6 .

What is an octet Class 9?

What is octet in chemistry class 9?

An octet of an electron means the presence of eight electrons in its outermost shell. This is the ability of an electron to gain, lose, or share their electrons with other elements to complete its octet.

How do I know if my octet is complete?

If there is a formal charge present in a compound, then the octet rule must be obeyed by looking at the bonds and lone pairs surrounding the formal charge. For example, an oxygen may take 3 lone pairs if bonded to one carbon but will have a negative formal charge.

What is octet and why is it inactive?

What is an Octet? An octet is an atom or an ion having eight electrons in the outermost shell of that atom. All noble gases except helium have eight electrons and are inert in nature. The electron configuration of a noble gas will always end as follows.

What follows the octet rule?

Atoms follow the octet rule because they always seek the most stable electron configuration. Following the octet rule results in completely filled s- and p- orbitals in an atom’s outermost energy level. Low atomic weight elements (the first 20 elements) are most likely to adhere to the octet rule.

What are two exceptions to the octet rule?

However, there are three general exceptions to the octet rule: Molecules, such as NO, with an odd number of electrons; Molecules in which one or more atoms possess more than eight electrons, such as SF6; and. Molecules such as BCl3, in which one or more atoms possess less than eight electrons.

What does the octet rule state?

The octet rule states that atoms gain stability when its outer valence shells comprise eight electrons. What does octet rule mean is that atoms of the main elements develop a tendency in participating in chemical bonding that the resulting molecule of every atom contains eight electrons in the valence shells.

What does octet mean in chemistry?

The octet noble gas configuration is an outer electron shell that contains 8 electrons, which is a stable arrangement, that most noble gases have (helium however, has only 2 outer electrons, because it is too small to have a second electron shell, as the other noble gases do). Octet simply means a group of 8. What do you mean by octet and duplet?

What is the octet rule for valence electrons?

The octet rule refers to the tendency of atoms to prefer to have eight electrons in the valence shell. When atoms have fewer than eight electrons, they tend to react and form more stable compounds. When discussing the octet rule, we do not consider d or f electrons. Only the s and p electrons are involved in the octet rule,

Why does sodium have an octet electron configuration?

Referring to the octet rule, atoms attempt to get a noble gas electron configuration, which is eight valence electrons. Sodium has one valence electron, so giving it up would result in the same electron configuration as neon. Chlorine has seven valence electrons, so if it takes one it will have eight (an octet).
