The Octet Rule is a principle in chemistry that says every atom prefers to have a complete outer shell of electrons, with eight electrons per shell, as this is a stable or low energy state. The electrons in the outermost shell are known as valance electrons and are important in bonding and creating molecules.

What is octet in simple words?
Definition of octet 1 : a musical composition for eight instruments or voices. 2 : a group or set of eight: such as. a : octave sense 2b. b : the performers of an octet.
What is octet in chemistry class 9?
OCTET: The possessing of 8 electrons in the outermost shell of an atom to make the shell fully filled is called as octet. Reason: Elements attain their octet by sharing or gaining electrons form another atom. Suggest Corrections. 3. Similar questions.
What is octet example?
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 an octet quizlet?
An octet is a group of eight electrons; in forming compounds atoms want to achieve the electron configuration of a noble gas. Duet rule.
What is an octet in Lewis structure?
Octet rule states that in forming compounds, atoms gain, lose or share electrons to give a stable electron configuration characterized by eight valence electrons. This rule is applied to the main-group elements of the second period.
Why is an octet needed?
The octet rule is important in covalent bonding because sharing electrons gives both atoms a full valence shell. All atoms strive to achieve a full valence shell, just like the noble gases. This is the most stable electron arrangement.
Why is an octet stable?
In chemistry, 8 isn’t a lucky number, per se, but, a number that indicates stability. The rule of 8 or the Octet rule is the tendency of atoms to have eight electrons in their valence shell. Eight electrons in this final shell allow atoms to be stable and non-reactive.
What is the octet rule and what is it based on?
It is based on the observation that the atoms of the main group elements have a tendency to participate in chemical bonding in such a way that each atom of the resulting molecule has eight electrons in the valence shell. The octet rule is only applicable to the main group elements.
What is Duplet and octet?
1) Number of electrons in outermost shell: The atom of an element having duplet configuration has only two electrons in the outermost shell, whereas the atom of an element having octet configuration has 8 electrons in its outermost shell.
What is an octet Class 9 Ncert?
Solution : An outermost shell which has 8 electrons is said to possess an octet.
What is octet rule Class 11?
The Octet rule states that main group elements try to bond with other atoms or species in such a way that all of them will possess stable electronic configuration. In other words we can also say that eight electrons in the outermost shell or valence shell of each atom.
What elements follow octet?
Elements that obey octet rules are the main group elements which are oxygen, carbon, nitrogen. s-block and p-block elements obey the octet rule except for hydrogen, helium, and lithium.
How do elements attain an octet?
Elements attain octet or stability by losing electrons, gaining electrons or by sharing electrons.
How do you find the octet?
What is the octet rule and why is it important quizlet?
What is the octet rule and how is it used in covalent bonding? The octet rule states that atoms lose, gain, or share electrons in order to acquire a full set of 8 valence electrons. In covalent an bonding the atom share electrons to achieve octet.
What is the octet rule and how is it used in determining covalent bonding?
The Octet Rule requires all atoms in a molecule to have 8 valence electrons–either by sharing, losing or gaining electrons–to become stable. For Covalent bonds, atoms tend to share their electrons with each other to satisfy the Octet Rule.
Does the atom satisfy the octet rule?
There are two ways in which atoms can satisfy the octet rule. One way is by sharing their valence electrons with other atoms. The second way is by transferring valence electrons from one atom to another.
How do you know if a octet is complete?
What atoms can break the octet rule?
Hydrogen, beryllium, and boron have too few electrons to form an octet. Hydrogen has only one valence electron and only one place to form a bond with another atom. Beryllium has only two valence atoms, and can form only electron pair bonds in two locations. Boron has three valence electrons.
Why is the octet rule not always 8?
The octet rule is based on the fact that each valence orbital (typically, one ns and three np orbitals) can accommodate only two electrons. To accommodate more than eight electrons, sulfur must be using not only the ns and np valence orbitals but additional orbitals as well.
What is the difference between octet and duplicate?
The key difference between octet and duplet is that octet is an atom or an ion having a maximum of eight electrons in the outermost shell while duplet is an atom having the maximum of two electrons in the outermost shell.
How many bytes is an octet?
In computers, an octet (from the Latin octo or “eight”) is a sequence of eight bit s. An octet is thus an eight-bit byte . Since a byte is not eight bits in all computer systems, octet provides a nonambiguous term.
What are octet and Duplet rule How do elements attain octet?
An atom having 8 electrons in its outermost shell is least reactive or most stable. If there is only one shell, then stability is attained by having 2 electrons in the shell and this is called duplet rule. Element attains octet in the following ways: (i) by losing or gaining electrons.
What is octet and why is it inactive?
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.
