Describe the nature of oxides formed by the extreme left elements of the s-block and elements on extreme right of the p-block. |
|
Answer» Elements on the extreme of a period easily combine with oxygen to form oxides. The normal oxide formed by the element in extreme left is the most basic (i.e., Na2O) whereas that formed by the element on extreme right is the most acidic (i.e., Cl2O7). Oxides of elements in the centre are amphoteric (e.g., Al2O3, As2O3) or natural (e.g., CO, NO, N2O). |
