Question

1)What is catenation?

2) What what is the the hardest element on the earth?

3) What is the atomic number of carbon?

4) Define inter-particle force?​​

Answer 1

⇝ Answer 1 :-

Catenation : Catenation is the ability of an atom to form bonds with other atoms of the same element.

--------------------------------

⇝ Answer 2 :-

Hardest element on the earth is diamond.

❒ Strucure of Diamond :

• Each carbon atom is joined to four other carbon atoms by covalent bonds.

• The carbon atoms have a regular lattice arrangement.

• There are no free electrons in Diamond.

--------------------------------

⇝ Answer 3 :-

Atomic Number of Carbon is 6.

❒ Additional Information :

• Atomic mass of carbon is 12

• Carbon is a p block element.

• Carbon belongs to 2nd period of periodic table

• Carbon is an element in group 4 (IUPAC group 14) of the periodic table.

• Each carbon atom can form four covalent bonds.

--------------------------------

⇝ Answer 4 :-

Inter - Particle Forces :

• Interparticle forces aur Intermolecular forces are forces due to which interaction between two or more molecules is present.

❒ Some Examples :

• Hydrogen bonding

• Ionic bonding

• Ion–induced dipole forces

• Ion–dipole forces

• Van der Waals forces – Keesom force, Debye force, and London dispersion force

Answer 2

Solution:-1

• Catenation is the ability of a atom to self-linking elements of another atom with itself .
• It depends upon the bond -energy,size and bond-length etc.
• Examples of Elements which show catenation:-carbon,silicon etc.

Solution:-2:-

• The hardest element on earth is diamond.
• Its a structure formed by covalent bonds of carbon atoms.
• There are no free atoms exist between structure of diamond .

Solution:-3:-

• Atomic number of carbon(C) is 6 .
• electronic configuration of carbon is $\sf 2s^22p^2$
• It belongs to group 13 and period 1 in periodic table.

Solution:-4:-

• Inter-particle force is the force between microscopic particles(like atoms,molecules) in a substance.
• It is highest in solid.
• It is lowest in gas.
