multiple bonds have _______ bond lengths and ________ bond energies | shorter, greater |
ability of an atom to attract electrons in a covalent bond | electronegativity |
nonmetals are (more/less) electronegative because they are trying to (gain/lose) electrons | more, gain |

what is the energy required to break the covalent bond? | bond energy |
WHATTTT exists between covalently bonded atoms with DIFFERENT ENs (aaalllmmmooosssttt always ;) | BOND POLARITY of course! |
the less the difference in EN, the greater the bond polarity(t/f) | FALSEEEE |
when is an bomded atom NONpolar?! | when: there is even sharing of electrons and even distribution of electrical charge |

attraction between the positive pole of one molecule and the negative pole of another | dipole-dipole |
the (more/less) polar the molecule, the greater the dipole-dipole attraction | more |

when do london forces become significant? | at low temperatures or in Large (ORGANiC) moleules |
London forces create an instantaneous dipole due to what? | random motion of electrons |
What is a strong attraction between metal cations and a mutually shared 'sea of electrons' | METALLiC BONDiNG |
