Octet Rule states that the atoms of the representative elements form bonds to obtain electronic configuration which is isoelectronic with noble gas. Atoms achieve noble gas configuration by
I transferring electrons
II donating electrons
III accepting electrons
IV sharing electrons
I and IV
II and IV
III and IV
II and III

What is the meaning of Dative Bond?
a covalent bond between two atoms where one of the atoms provides both electrons that form the bond.
a covalent bond between two atoms where both of the atoms provides both electrons that form the bond.
same with an ionic bond
not exist
What is the Lewis symbol of a carbon?
All are correct

Never exist
Are lost in space
are electrons are shared with another atom in a covalent bond
are electrons not shared with another atom in a covalent bond
