What is an octet of an electron?

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. Octet Rule Examples. A few examples which follow the octet rule are : CO 2, NaCl, MgO. 1.CO 2. Carbon contains four electrons in its outermost shell.

How many electrons does carbon need to complete its octet?

1. What is the difference between the octet of an electron and a valence electron?

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 it...

2. Why do elements complete their octet?

The octet rule states that when an element loses, gains, or shares its outermost electrons to complete their octet state with a set of eight electr...

3. In what way is the octet rule useful?

The octet rule helps us predict the chemical behaviour of the elements. It helps us understand that an atom is most stable when it has valence shel...

4. Does the O2 molecule satisfy the octet configurations?

The octet rule helps us predict the chemical behaviour of the main group elements. It helps us understand that an atom is most stable when it has v...

5. Name any four elements that disobey the octet rule.

We all know that 1p shell does not exist hence many atoms attain stability in the 1s2 configuration itself. While on the other hand, some elements...

What are the exceptions to the octet rule?

Some of the exceptions about octet rule are given below: An electron or molecule which contains unpaired electrons in its outermost shell or valence shell is considered as free radical. These electrons are less stable and do not obey the octet rule.

What is the octet rule?

The octet rule states that the elements which can lose, gain, or share electrons from its outermost shell to complete the valence shell with a set of eight electrons. Valence electrons mean the total number of electrons present in the outermost shell of an element that can participate in the bond formation. ...

Which element is more stable?

An electron that contains a complete outermost shell or half-filled is said to be more stable whereas electrons less than half-filled are unstable and can easily lose their electrons. Noble gases are said to be highly stable elements. Those elements which follow octet rule are said to be more stable.

When an element loses, gains, or shares its outermost electrons to complete its octet

The octet rule states that when an element loses, gains, or shares their outermost electrons to complete their octet state with a set of eight electrons then it Is said that they are following the octet rule. Elements follow the octet rule to become more stable as complete filled outermost shells have a strong and balanced force between protons and the electrons.

How many valence electrons does Cl have?

So we can say the Valence electron for Cl is 7. When both sodium and chlorine combine and share their electron and have eight electrons in their outermost shell then it is said that the compound formed follows the octet rule.

How many electrons does carbon have?

Carbon contains four electrons in its outermost shell. Also, carbon should have four electrons to complete its octet when it is combining with two molecules of oxygen. Here each carbon atom requires two electrons to complete its octet. Carbon and oxygen share their outermost electron and form CO2 which further completes the octet.
