Electronegativities of the elements (data page)

Electronegativity (Pauling scale)

Notes

• Separate values for each source are only given where one or more sources differ.
• Electronegativity is not a uniquely defined property and may depend on the definition. The suggested values are all taken from WebElements as a consistent set.
