Question

Arrange the following elements in order of increasing electronegativity:
lead, astatine, polonium, bismuth

smallest:

largest:

Answer 1

Answer #1

the given elements all belong to the same period in the periodic table

now

the trend is that

along the period from left to right , electronegativity increases

in the periodic table they are arranged as follows

Pb Bi Po At

so

At will have the highest EN value and Pb will have the lowest

so

the order is

smallest , Pb < Bi < Po < At , largest

smallest , lead < bismuth < polonium < astatine , largest
