Electronegativity Trends And Chemical Bonding

Noble gases are generally excluded from standard electronegativity trends.

Electronegativity generally increases from left to right across a period and from bottom to top within a group, excluding most transition metals and noble gases.

A slight difference in electronegativity between two atoms results in the formation of a polar covalent bond.

When the electronegativity values of two atoms are approximately equal, a nonpolar covalent bond forms.

All of these statements are true.
