1.	State whether the following statement is ‘True’ or ‘False’. Correct the false statement.(1) Molecular state of oxygen is monoatomic. (2) The capacity of an element to combine is called its valency. (3) Anionic radicals are basic radicals. (4) The magnitude of charge on any radical is its atomic number. (5) In a chemical reaction, mass of original matter and mass of matter newly formed as a result of chemical change are equal. (6) The proportion by weight of carbon and oxygen in carbon dioxide is 3 : 5. (7) Relative mass of hydrogen is 1. (8) The number of molecules in a given quantity of a substance is determined by its atomic mass. (9) Avogadro’s number is 6.022 x 1023 (10) Valency of sodium is 2.
