2.2C Bond Polarity

What is Electronegativity?

an element is a measure of the ability of its atoms to attract electrons in a covalent bond

Why does Electronegativity increase for each period/group

Period:

• increase to the right due to the increase in nuclear charge, resulting in increased attraction to electron

Group:

What is bond polarity?

• if two atoms with different electronegativities are bonded together, the more electronegative atom will pull electron towards itself

• the electron distribution will not be symmetrical

What are dipole molecules?

a molecule where a concentration of positive charge is separated from a concentration of negative charge

What is the electronegativity of a non-polar covalent bond?

Tell me about the Bonding Continuum

more polar = more like ionic compound
