<u>Answer:</u> The pair of valence electrons that do not participate in the bonding are lone pairs.

<u>Explanation:</u>

There are 2 types of pair of electrons that are studied in the bonding. They are:

  • <u>Bonding pairs:</u> These pair of electrons participate in the bond formation. They exist as bonds in a molecule. They are also known as bond pairs.
  • <u>Non-bonding pairs:</u> These pair of electrons do not participate in the bond formation. They exist as lone pairs in a molecule.

Oxygen is the 8th element of the periodic table having electronic configuration of 1s^22s^22p^4

Number of valence electrons = (2 + 4) = 6

Oxygen needs 2 electrons to complete its octet. When another oxygen combines, they share 2 electrons each forming a double bond.

The Lewis dot structure of oxygen molecule is given below.

Hence, the pair of valence electrons that do not participate in the bonding are lone pairs.

Answer:

Nonbonding pairs of electrons.

Explanation:

Both oxygen atoms in the diatomic molecule have two nonbonding pairs. This results in the oxygen molecule having a planar geometric shape. This is because nonbonding pairs repel each other are significant in determining the shape of a molecule.

Describe the electron distribution in a polar-covalent bond and it's effect on the partial charges of the compound?
Artemon [7]

Answer:

In polar Covalent bonds, the electrons which are in bonded shifts towards an atom which has more valance electrons.

<u>Explanation:</u>

We know if an atom takes the electron it acquires a negative charge whereas if it gives an electron it acquires a positive charge in the ionic bond. But here we are talking about covalent bonds. Covalent bonds are those in which atoms share the electron instead of completely giving off the electron. If the atoms are identical in case of covalent bond that is 2 hydrogen atoms then this type of bonding is called pure covalent bonds but if the atoms linked in covalent bonds are different then it is called polar covalent bonds.

In this, the bonding electrons will shift towards an atom which has more valence electron thereby acquiring the partial negative charges and the other atom will acquire a partial positive charge. For example, HCl. In this the Chlorine atom is having more valence electron than hydrogen atom, and hence Chlorine atom has a partial negative charge and Hydrogen atom has a partial positive charge.

Easons for the dense packing in metals <br>​
Firdavs [7]

Explanation:

Typically, only one element is present, so all atomic radii are the same. -Metallic bonding is not directional. -Nearest neighbor distances tend to be small in order to lower bond energy.
