- The genetic material is DNA, which contains all the information of our genetic code. It stays in the nucleus of eukaryotic cells, in prokaryotes it is dispersed throughout the cytoplasm.

Explanation:
a) Three types of chemical bondings:
- Ionic bonding: Complete transfer of electrons from an electropositive atom to an electronegative atom.
- Covalent bonding: Equal sharing of electrons between the atoms with less or zero electronegativity difference.
- Metallic bonding: The bonding between the conduction electrons(electron cloud of delocalised electrons) and positively charged metal ions
b) Those elements are named as Noble gases which inert in nature that is less reactive due to fully filled electronic configuration.
Their general electronic configuration is given by:
n = principle quantum number
c) In an ionic bonding, electrons are transferred to the electronegative atom from the electropositive atom.
Electronegative: An atom which gains an electrons.Negative charge carrying ion is formed.
Electropositive : An atom which looses electrons.Positive charge carrying ion is formed.
d) This because the band width between the conduction band and valence band is large due to which electrons will not able to jump from valence band to conduction band.This makes the non metal poor electrical conductors.
