Question

Расположите элементы в порядке уменьшения электроотрицательности: As CL Br F Se

Answer 1

Elements in Decreasing Electronegativity Order

The elements arranged in decreasing electronegativity order are: F, Cl, Br, Se, As.

Here is the order of the elements based on their electronegativity:

1. Fluorine (F): Fluorine is the most electronegative element and has the highest electronegativity value among the elements listed. 2. Chlorine (Cl): Chlorine has a lower electronegativity than fluorine but is still more electronegative than the remaining elements. 3. Bromine (Br): Bromine has a lower electronegativity than chlorine but is more electronegative than selenium and arsenic. 4. Selenium (Se): Selenium has a lower electronegativity than bromine but is more electronegative than arsenic. 5. Arsenic (As): Arsenic has the lowest electronegativity among the elements listed.

Please note that electronegativity values can vary depending on the scale used, so the order may change slightly depending on the specific scale used for comparison.
