Answer:
Fe(NO3)3 is ionic.
Explanation:
Ionic bond:
Ionic bond is formed when oppositely charged ions attract each others i.e negative and positive ions.
We know that a neutral atom consist of equal number of proton and electron, cancel the charge of each other that is equal in magnitude and make the atom neutral or we can say that net charge is zero.
But when the atom lose or gain the electron, imbalance of neutron electron occur so charge will not remain zero and atom is no more to be said neutral.
In given compound Fe(NO3)3 the Fe is act as cation while nitrate is act as anion.
3Fe+ (Cation)
3NO3 ∧ -1 (anion)
3Fe∧+1 + 3NO3 ∧ -1 → Fe(NO3)3
Another example of ionic compound:
Now consider the sodium chloride which is an ionic compound. It is formed by the complete transfer of electron from sodium to chlorine atom and form ionic bond. In this ionic compound sodium carry positive charge and chlorine carry negative charge there is attraction between these oppositely charged atoms.
Na+ (cation)
Cl- (anion)
NaCl
Covalent bond:
Covalent bond involve the sharing of electrons between the atoms. It is also called molecular bond. These electron pairs are called bonding electrons are shared pair of electrons.
