Put the elements potassium iron bromine and krypton in order of increasing electro negativity

K < Fe < Br < Kr

Explanation:

Given chemical elements;

      Potassium

      Iron

      Bromine

      Krypton

Problem; arrange in order of increasing electronegativity

Solution:

The electronegativity of an element measures the relative tendency with which the atoms of the element attracts valence electrons in the chemical bond.

 To solve this problem, we are going to use values of electronegativity from the Pauling's electronegativity table of elements;

       For;

            Potassium  = 0.8

            Iron = 1.83

            Bromine  = 2.8

            Krypton = 3.0

So;

  K < Fe < Br < Kr

output?
