Ionic Bonding Atoms lose or gain electrons, so their outer shell is completely full.
Ionic compounds- regular lattice structure -Giant ionic lattices -Form a closely packed regular lattice -very strong electrostatic forces of attraction- oppositely charged ions
Ionic compounds- Similar properties - high melting points -high boiling points - strong attractions - ionic compounds melt- ions free to move& carry electric current -dissolve in water easily - ions separate& are free to move in the solution so they'll carry electric current
Isotopes Different atomic forms of the same element- same number of protons but different number of neutrons
Proton charge -> +1P
Neutron charge -> +1N
Electron charge -> Very small/ negligible
23 Na 11 -mass number= big number -atomic number= little number
Number of neutrons? Subtract the atomic number from the mass number
Covalent bonding -sharing electrons with other atoms - only share electrons in the outer shell -both atoms have full outer shells

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.
