arrange the following elements in order of increasing electronegativity (top element has the lowest and bottom element with the highest EN)

Question

Cs
Al
Fr
Si

arrange them in the desired order.

Answer 1

To arrange the elements Cs (Cesium), Al (Aluminum), Fr (Francium), and Si (Silicon) in order of increasing electronegativity:

1. Fr (Francium) - lowest electronegativity
2. Cs (Cesium)
3. Al (Aluminum)
4. Si (Silicon) - highest electronegativity

So the order from lowest to highest electronegativity is: Fr < Cs < Al < Si.
