QuestionAnswer
Element any pure substance that is made of onle one kind of atom
Aristotle Believed Air, Fire, Earth, and Water

how many elements 117
how many are natural 92
how many are solid at room temp 13
how many are gases 11
Diatomic Elements Hydrogen, Nitrogen, Oxygen, Florine, Chlorine, Bromine, and Idione
Arranged first periodic table Dmitri Mendeleev
Periodity the repetition of certain properties at regular intervals when elemtns were placed in order of atomic MASS
Every 8th Octaves
Group Down
Period Across
Family Down
Series Across
Metals Tehy belong to families with relatively few valence electrons. These valenve electrons are not held very strongly and are easily removed.
Non metals hold their electrons tightly, so their properties are very different from metals
Metals Prop Luster, malleable, conduct electrity, and ductile
Non metal Prop Lack luster, brittle, can't conduct, and not ductile.
Atomic diameter DOwn and uP
The Second Law of Thermodynamcis All natural processes move toward a state of minimum energy
Ocet Rule atoms generally are most stable when they have a full 8 valence electrons
Atoms can gain, lose, or share electons to get the octet
Electron Affinity deals with the strength of attrraction of electrons to UNBONDED ATOMS.
Electronegatvity deals with an atom's ability to attract and hold electrons when BONDED TO OTHER ATOMS
Covalent bond Non-metal/Non-metal sharing
Ionic bond Metal/Non-metal Give or Take
Metallic bond Metal/Metal Everyone Shares
Periodic law of the elements The properties of the elments vary with their atomic numbers in a periodic way

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.
