Atomic number of an element is 16. Predict (i) the number of valence electrons in its atom (ii) its valency (iii) its group number (iv) whether it is a metal or a non-metal (v) the nature of oxide formed by it. (vi) the formula of the chloride
The element with atomic number Z = 16 is sulphur. The electronic configuration of the element is 2, 8, 6. (i) The number of valence electrons is 6 (ii) The valency of the element is 2 (8 – 6 = 2) (iii) The group number of the element is 16. (iv) The element is a non-metal. (v) Since the element is non-metal, its oxide is acidic in nature. Actually, two oxides are formed. These are SO2 and SO3. Both are of acidic nature. (vi) The formula of the chloride is SCl2.
