Class 11 -Chemical and Ionic Bonding

Front

What is the valency of an atom of metal derived from Lewis Structures?

Back

The valency can be obtained by the summation of the number of electron dots.

Front

What type of bond is present in MgBr2?

Back

Ionic bond.

Front

What occurs during the formation of a chemical bond in terms of potential energy?

Back

There is a decrease in potential energy.

Front

Which statement about ionic solids is incorrect?

Back

They conduct electricity in solid state.

Front

Which element neither loses nor gains electrons?

Back

Carbon.

Front

Define ionic bond.

Back

An ionic bond is a type of chemical bond that involves the electrostatic attraction between oppositely charged ions.

Front

What is the main characteristic of ionic compounds in terms of solubility?

Back

Ionic compounds are generally soluble in water.

Front

What is the typical melting and boiling point of ionic solids?

Back

Ionic solids have high melting and boiling points.

Front

Explain the role of electron transfer in ionic bonding.

Back

In ionic bonding, one atom transfers electrons to another, resulting in the formation of positively and negatively charged ions.

Front

What is the difference between covalent and ionic bonds?

Back

Covalent bonds involve the sharing of electron pairs between atoms, while ionic bonds involve the transfer of electrons.
