Periodic Trends in Electronegativity

Key Questions

• What trends in electronegativity occur in a period?

  The trends for electronegativity is that the value increases across the periods (rows) of the periodic table. Lithium 1.0 and Fluorine 4.0 in period 2

  The electronegativity also increases up a group (column) of the periodic table. Lithium 1.0 and Francium 0.7 in Group I.

  Therefore Francium (Fr) in the lower left Group I Period 7 has the lowest electronegativity value at 0.7 and Fluorine (F) upper right Group 17 Period 2 has the highest electronegativity value at 4.0.

  I hope this was helpful.

• What is the definition of electronegativity?

  Answer:

  The tendency of an atom in a molecule to attract the shared pair of electrons towards itself is called its electronegativity

  Explanation:

  Electronegativity is a dimensionless property since it is only a tendency. It only indicates the net result of the tendencies of different elements to attract the bond forming electron pair.
