VSEPR stands for Valence Shell Electron Pair Repulsion
Tetrahedron has the angle of... 109
Pyramdial has the angle of.. 107
Non bending electrons pairs tend to ____ more than bonding electron pairs repel
H2O has the angle of... 105
Trigonal has the angle of... 120
Linear molecule has the angle of... 180
If there are 3 groups of electrons around the central atom, then the shape is _____ with a bond angle of ____ trigonal, 120
If there are four groups of electrons around the central atom, the basic shape of the atom is.... a tetrahedron, with a bond angle of 109
If the central atom ahs one pair of non-bonding electrons, then you have a tetrahedron with one leg removed. This result in a _______ shape, with a bond angle of about ____ pyramdial, 107
If two bonding electrons pairs surround the central then two legs of the tetrahedron are missing. This ens up giving the molecule a ____ shape, with of bond angle of about ____ bent, 105

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.
