Answer 2

The order of elements based on increasing electronegativity is as follows:

а) Cl, F, Si, Al б) C, B, Be, Li в) B, C, N, F г) V, P, Se, N

Electronegativity is a measure of an atom's ability to attract electrons towards itself in a chemical bond. It increases as you move across a period from left to right in the periodic table and decreases as you move down a group.

Here is the order of elements based on increasing electronegativity for each option:

а) Cl (chlorine) < F (fluorine) < Si (silicon) < Al (aluminum) б) C (carbon) < B (boron) < Be (beryllium) < Li (lithium) в) B (boron) < C (carbon) < N (nitrogen) < F (fluorine) г) V (vanadium) < P (phosphorus) < Se (selenium) < N (nitrogen)

Please note that the order of elements based on electronegativity may vary slightly depending on the specific values used for electronegativity. The values used here are approximate and based on general trends in the periodic table.
