AP Chem Exam Review

True or False? Nuclear charge increases across a period. True. Since the number of protons increase as you go across a period, so does the nuclear charge.
True or False? Radius increases as you go across a period. False. Since the nuclear charge increases across a period, electrons are bound tighter together therefore the radius decreases.
True or False? Ionization increases across a period? True. Since the amount of electrons increase, so does the ionization.
True or False? As you go down a group, the number of valence shell electrons decrease. False. Valence electrons increase as you travel down a group on the periodic table.
True or False? Radius increases as you go down a group. True. Since valence electrons increase, the radius increases.
True or False? Ionization energy increases down a period. False. Electrons are further from the nucleus therefore the ionization energy decreases.
What charge is an anion? Negative
What charge is a cation? Positive
What does a mass spectroscopy show? The relative abundances of isotopes
What is an isotope? A variation of an element that possesses the same atomic number but a different mass number.

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.
