=> Potassium sulphate:- Ionic bond is formed,wherein potassium loses electrons & sulphate gains electrons
=> Tin:- Tin can form two ions Sn 2+ or Sn4+ now depending on what form it is in and what other element it is bonding with then only the type of bonding will be known
=> Benzene:- it is comprise of sp2 hybridized carbon atoms which makes covalent bond with each other by mutual sharing &pairing of electrons
=> Urea:- Polar molecular solid & they mostly forms hydrogen bond with other atoms
=> Ammonia:- covalently bonded polar compound formed by mutual sharing & pairing of electrons between nitrogen & three hydrogen atoms
=> Water:- covalently bonded polar compound formed by mutual sharing of electrons between oxygen & hydrogen atoms
=> Zinc sulphide:- it exist in the form of crystals & makes coordination bond
=> Graphite:- it consist of carbon atoms & have covalent bond between them forming a 2-D (flat, planar etc.) network, which in itself is strong. These planes are then held together by London Forces, which are very weak.
=> Rubidium:- Metallic bond is formed by rubidium because it is a metal.Metallic bond is hydrid of covalent bond & ionic bond
=> Argon:- Non-polar molecular solid
=> Silicon carbide:- Covalent or network solid
