CHEM FINAL

QuestionAnswer
Calculate the average atomic mass of oxygen, if its abundance in nature is 99.76% o16, 0.04% o17, and 0.20% o18 (16)(99.76) + (17)(0.04) + (18)(0.20) ------------------------------------------ 100
Atomic Mass Below Chemical letter
Atomic Number Above Chemical letter
Where to find protons Same as the Atomic number
Where to find Electrons Same as protons (unless charged)
Ionization Energy Right and Up (Increase)
Atomic Radius Left and Down (Increase)
Electronegativity Right and Up (Increase)
Ionic Bond Transfers, Conducts Electricity, High melting and Boiling points, Hard and brittle, Soild at room temp
Covalent Bond Shares, Does not conduct electricity, Low melting point and low boiling point, Mostly gas and liquid at room temp, Two NON-METALS
Non-Polar, Polar, Ionic 0-0.4 Non-Polar 0.5-.17 Polar 1.8+ Ionic
Combustion C1 H2 03 ----> H20 CO2
Empirical Formula Simplifying charges
Bent Lone pair
Tetrahedral T shape
Trigonal Planar No lone pairs
Trigonal Pyramind Lone pair

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.
