Question
For the main group of the periodic table, the metallic properties of the elements vary approximately with their position as shown in the table.
| 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 |
| H | He | ||||||
| A | B | ||||||
| C | D |
Will the most non-metallic element be found at A,B,C or D ?
Solution
The most non-metallic element will be found at D.
