Question

What is the difference between electrovalent and covalent bonding

Answer 1

Heyaa!!

ELECTROVALENT ( IONIC BOND)

★ 】 It is formed when there is complete ransfer of electrons from one atom another

★ 】such compound are called ionic compound

★】 Their constituent particles are ion

★ 】They have hard solids consisting ions

★】 these are non - volatile with high boiling point and melting point

★】 They dont conduct electricity in solid state but known as good conductor of electricity in liquid , fuse ,or molten state

★ 】these compound are soluble in water

COVALENT BOND

★】 this bond is formed when there is sharing of electron between the same or different species atom of an element

★ 】 Their constituent partilcles are are molecules

★】its compound are gases liquid or soft solid ( except graphite and diamond)

★】its compiunds are volatile with low boiling and low melting point

★ 】they are non conductor of electricity in solid , molten state

★】its compounds are insoluble in water

Answer 2

Electrovalent:

•Complete transfer of electrons

•Ions are involved

•Electronegativity value diff by a value of more than 1.7

Covalent:

•Sharing of electrons

•Atoms are involved

•Electronegativity value diff by a value of less than 1.7
