Covalent Bond The sharing of electrons between nonmetals
Single Bond 2 electrons shared
Double Bond 4 electrons shared
Triple Bond 6 electrons shared
Compound 2 or more elements chemically combined
Octet Rule Atoms will gain, lose, or share electrons in order to have 8 electrons in their outer energy shell
Stability Full/complete outer energy level of valence electrons
Ions Atoms that have a charge due to having lost or gained electrons
Cations Positively charged ions; atoms or molecules that have lost e-; usually metals
Anions Negatively charged ions; atoms or molecules that have gained e-; usually nonmetals
Oxidation Number The charge of an ion within a compound
Group 1 elements have 1 valence e-; +1 charge

Group 13 elements have 3 valence e-; +3 charge
Group 14 elements have 4 valence e-; +/- 4 charge
Group 15 elements have 5 valence e-; -3 charge
Group 16 elements have 6 valence e-; -2 charge

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.
