Week 19 Vocab

Front

Atom loses electrons easily reacts with one that has high electron affinity, forming an ionic compound.

Back

ionic bond

Front

Electrons equally shared by nuclei, typically between nonmetals.

Back

covalent bond

Front

Atoms with unequal electron sharing create "poles" with partial charges.

Back

polar covalent bond

Front

A molecule with positive and negative charge centers

Back

dipole

Front

Separation of positive and negative charges in a molecule

Back

dipole moment

Front

Energy needed to break a mole of molecules into atoms; strength of a chemical bond; also called bond enthalpy.

Back

bond energy

Front

Energy stored in atomic bonds; higher means harder to break.

Back

enthalpy

Front

Localized electron pairs on an atom that repel more than bonding pairs.

Back

lone pair

Front

Pairs of electrons in the space between bonded atoms; show less repulsion than lone pairs.

Back

bonding pair

Front

Polar covalent compounds...

Back

aren't always dipoles.
