different groups in the periodic table, and their characteristics.

GroupCharacteristics
alkali metals extremely reactive, never found in nature, one valence electron

CHNOPS this is not a group, they are elements formed in life
lanthanides transition metals at the bottom of the chart, shiny + reactive
noble gases unreactive non-metals, colorless and odorless at room temperature
halogens all non-metals, extremely reactive, poor conductors of heat + electricity, tend to form salts
transition metals moderate range of reactivity, range of properties, shiny, good conductors of heat + electricity
basic metals metals past the transition metals, more valence electrons, brittle, low melting points
metalloids between metals/non-metals in properties, appear to be metals, brittle, poor conductors
hydrogen sun burns hydrogen, one electron, simplest atom, diatomic, reactive gas, family of its own
non-metals doesn't have the properties of metals, can be solids, liquids, or gases, makes negative ions, gains electrons

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.
