The electronegativities (according to Pauling) of the elements in period 3 of the periodic table are as follows with elements arranged in alphabetical order:
| Al | Cl | Mg | Na | P | S | Si |
| 1.5 | 3.0 | 1.2 | 0.9 | 2.1 | 2.5 | 1.8 |
Arrange the elements in the order in which they occur in the periodic table from left to right.
(The group 1 element first, followed by the group 2 element and so on, up to group 7).
