lewis dot structure an electron configuration notation in which only the valence electrons of an atom of a particular element are shown , indicated by dots placed around the elements symbol
octet rule an atom will be most stable when surrounded by 8 electrons in the valence shell (outer most energy level)
metallic bond a bond formed by the attraction between positively charged metal ions and the electrons around them

polar describes a molecule in which the positive and negative charges are seperated
non-polar A covalent bond in which the bonding electrons are equally attracted to both bonded atoms
bent 2 atoms bonded and 2 lone pairs
tetrahedal 4 bonded atoms and 0 lone pairs
trigonal planner 3 bonded atoms and 0 lone pairs
linar 2 binded atoms and 0 lone pairs

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.
