State which is not a typical property of an ionic compound. A: high m.p. B: Conducts electricity in moltern & in the aq. Soln. state. C : Are insoluble in water. D: Exist as oppositely charged ions even in the solid state.

An ionic compound conducts electricity even in the solid state due to the presence of ions.

Give reasons why? Ionic compounds do not conduct electric current in the solid state

Identify the type of cyrstalline solid based on the following properties : (a) Conducts electricity in the molten state but in the solid state. (b) Very hard with melting point and acts as electrical insulator. (c) Conducts electricity in the solid state, malleable and ductile.

State which of the following is a common characteristic of a covalent compound. A. High melting point B. Consists of molecule C. Always soluble in water D. Conducts electricity when it is the moltern state.

Explain the following: (a) Sodium chloride is an ionic compound which does not conduct electricity in solid state whereas it does conduct electricity in molten state as well as in aqueous solution. (b) Reactivity of aluminium decrease if it is dipped in nitric acid. (c) Metals like calcium and magnesium are never found in their free state in nature.

Explain the following: Covalent compounds do not conduct electric current in the fused state, whereas ionic solids do.

Name the following: (a) A transition metal which does not exhibit variation in oxidation state in its compounds. (b) A compound where the transition metal is the +7 oxidation state. (c) A member of the lanthanoid series which is well known to exhibit +4 oxidation state. (d) Ore used in the preparation of Potassium dichromate.

Ionic bond is defined as the electrostatic force of attraction holding the oppositely charged ions. Ionic compounds are mostly crystalline solid having high melting and boiling points, electrical conductivity in moleten state, solubility in water etc. Covalent bond is defined as the force which binds atoms of same or different elements by mutual sharing of electrons in a covalent bond. Covalent compounds are solids, liquids or gases. They have low melting and boiling points compounds. They are more soluble in non-polar solvents. The amount of energy released when one mole of ionic solid is formed by packing of gaseous ion is called :
