Chem. Exam

Review for Exam 1

TermDefinition
Orbital diagram 1 is a violation of Aufbau Principle The +1 orientation has an electron before the -1 & 0 orientation
Orbital diagram 2 is a violation of Hund's Rule The -1 orientation has paired spins before the 0 & 1 orientation has spins
Orbital diagram 3 is a violation of Pauli Exclusion Principle The 0 orientation has two parallel spins meaning, both electron has the same 4 quantum number
Metals (Ca) Lose electron to form cations so r^atom > r^cations
Nonmetals (Br) Gain electron to form cations so r^atom < r^anion
Indicate how the number of electrons changed when these atoms (Ca) and (Br) formed ions Ca & Br are in the same period & atomic radius decreases from left to right r^Ca > r^Br

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.
