Electronegativity increases as we move from left to right across a period and decreases as we move down a group. Cs is in Group 1 (alkali metals) and has the lowest electronegativity among the three elements. F is in Group 17 (halogens) and has the highest electronegativity among the three elements. P is in Group 15 and has a higher electronegativity than Cs but lower than F. Therefore, Cs < P < F in terms of increasing electronegativity.
