QuestionAnswer
What is periodic law? In order of atomic number, properties of elements that change across, repeat themselves in the next row.
Periodic Table Arrangement: - A (IA to VIIIA) - B (IB to VIIIB) - two rows below A - main group (1-20) B - transitional metals Lathanides & Actinides
What does the diagonal separate? The diagonal line separates metallic from non-metallic elements.
Properties of metals: Conduct heat and electricity; Shiny in appearance; Malleable (can be easily shaped); Solid at room temperature (exception: liquid mercury)
Properties of non-metals: Do not conduct heat and electricity; Dull in appearance, many colours; Brittle; Liquid or gas at room temperature
What is group IA? What are its properties? Alkali Metals; Highly reactive - stored in oil to avoid reacting with air or moisture
What is group IIA? What are its properties? Alkaline earth metals; Not as highly reactive - do not need to be stored in oil
What is group VIIA? What are its properties? Halogen Family; Highly reactive non-metals
What is group VIIIA? What are its properties? Noble gas family; Most stable and least reactive elements known
Three main periodic trends: 1) Atomic Radius 2) Ionization Energy 3) Electronegativity
Atomic Radius trend: 1) Atomic sizes get larger as you move down a family - added energy level increases atomic size and radius 2) Atoms get smaller as you go across a period. - more e- in outermost level gives stronger nuclear charge, pulls inward, shrinking atom and radi
First Ionization Energy trend: 1) I.E. decreases down a family 2) I.E. increases across a period

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.
