Ch. 17-18 Physics

TermDefinition
Diatomic Elements H,N,O,F,Cl,B,I (add sub 2's below each)
Periodic Law of Elements The properties of elements vary a periodic or reoccuring pattern with their atomic #'s.
Electron Affinity Deals with the strength of attraction of electrons to unbonded atoms.
Ionic Bonds Giving away and taking electrons (Metals/NonMetals)
Covalent Bonds Sharing electrons (non metals)
Metallic Bonds Everyone shares electrons (Metals)
Periodicity The repetition of certain properties at regular intervals when elements were placed in order of atomic mass.
Dmitri Mendeleev arranged the elements into what is now known as the periodic table. He left BLANK SPACES
Johann Dobereiner Arranged the elements into triads.
How man naturally occurring elements are there? 92
Cations positive
Anions negative
Monotomic Elements He, Ne, Ar, Kr, Xe, Rn (all noble gases)
Electron Negativity deals with an atom's ability to attract and hold electrons when bonded to other atoms
Electron Sea Theory Atoms with weak electronegativities usually have only a few loose valence electrons
What does the family group tell you? How many valence electrons are in an element
What does the period tell you? How many energy levels an element has.
Metals Luster, Malleable, Conduct Electricity, Ductile
Non Metals Lack Luster, Brittle, Don't Conduct Electricity, Not Ductile.
Octet Rule Atoms are only happy when they have 8 electrons in their valence energy level.

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.
