Give reasons :A non-metallic atom (at. no. 9) forms a molecule of the same, containing a single covalent bond. |
|
Answer» Electronic configuration of non-metallic element (say X) with atomic number 9 is ; K L X (Z = 9): 2, 7 Thus it requires one electron to complete its octet and attain stable structure of nearest noble gas (Ne). To do this each of the two ‘X’ atoms contributes one electron so as to have one shared pair of electrons between them. Both atoms attain stable doublet structure, resulting in the formation of a single covalent bond between them as shown below: |
