Chemistry unit 11

TermDefinition
Ionic Bonding Chemical bonding that results from the electrical attraction between cations and anions
Covalent Bonding results from the sharing of electron pairs between two atoms
Electronegitivity nonpolar-covalent 0-0.3
Electronegitivity polar-covalent 0.4-1.7
Electronegitivity ionic >1.7
VSEPR theory predicts the shape of some molecules and assumes that pairs of valence electrons surrounding an atom repel each other
What atom goes in the middle in a 3 atom compound? Carbon or the least electronegitive atom
Hydrogen Bonding The intermolecular force in which a hydrogen atom that is bonded to a highly electronegative atom isattracted to an unshared pair of electrons of an electronegative atom in a nearby molecule
What does VSEPR stand for? valence-shell, electron-pairrepulsion
AX2 Linear && 180
AX3 Trigonal Planar && 120
AX4 Tetrahedral && 109.5
AX5 Trigonal Bipyramidal && 120/90

Boiling points for molecules Metallic>Ionic>Polar-Covalent>nonpolar-Covalent
dipole-dipoleforces The forces of attraction between polar molecules

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
