True or False
______ 1. Oxygen is the most abundant of the elements.
______ 2. Equal volumes of all gases under the same pressure and temperature contain
the same number of molecules.
______ 3. Valences of the same element could either be positive or negative.
______ 4. Ozone is the allotrope of oxygen.
______ 5. Metal oxides as well as non-metal oxides react with water to form hydroxides.
______ 6. At constant temperature, the volume of a gas varies inversely with the
pressure.
______ 7. The three states of matter are solid, liquid and gas.
______ 8. In the triclinic crystals system, three axes of equal length intersect each other
at oblique angles.
______ 9. Chemical equilibrium is a state where reactions are opposite in effect and
have the same velocity.
______ 10. Lithium, potassium and sodium are called alkali metals.
______ 11. The periodic law states that properties of the chemical elements are periodic
functions of their atomic weights.
