Question

As atoms of elements in Group 16 are considered in order from top to bottom, the electronegativity of each successive element

Answer 1

The electronegativity of the 16 group elements is decreasing from top to bottom

Answer 2

The value of electronegativity is as follows-

O-3.44

S-2.58

Se-2.55

Te-2.1

Po-2.0

• Electronegativity of a species is defined as its electron attracting power.
• The group 16 elements are O, S, Se, Te and Po.
• Among the group 16 elements as we move from Oxygen to Po the value of electronegativity decreases because the size of the atom increases and its distance from the nucleus decreases.
• Hence the value of electronegativity is as follows-

O-3.44

S-2.58

Se-2.55

Te-2.1

Po-2.0
