Question 17 :
Assertion: Ionic compounds are bad conductors of electricity. Reason: In ionic compounds mobile ions exists.

Question 19 :
Assertion: Covalent bonds are broken when sugars are dissolved in water. Reason: In molecules with covalent bonds, electrons are shared by two or more atoms.

Question 20 :
Elements $A, B$ and $C$ have respectively $1,3$ and $5$ electrons in valence shell. Ionic compound is not formed from :

Question 22 :
During the formation of sodium chloride, chlorine accepts one electron from sodium to attain the configuration of which noble gas?

Question 24 :
Assertion: Covalency of oxygen atom is three. Reason: There are three unpaired electrons in Oxygen atom.

Question 27 :
The correct electronic configuration of neutral $Ca$ and $O$ are respectively:

Question 29 :
Assertion: The bond between two identical nonmetal atoms has a pair of electron with identical spin. Reason: Electrons are transferred fully from one atom to another.

Question 30 :
Assertion: Ionic compounds have high melting and boiling points. Reason: Ionic compounds are solids and hard due to strong force of attraction between positive and negative ions in their molecules.
