York Bio Quiz 1

QuestionAnswer
atomic number number of protons, determines which element it is
Element A substance that can not be broken down into any other substance
mass number the sum of the number of protons and neutrons
isotopes variant mass forms of an element
radioactive isotopes when the nucleus decays, giving off particles and energy. can be used as tracers for medical purposes.
electron configuration how energy shells contribute to chemical properties
ionic bonds the bonds that result from electrons being exchanged between atoms to fill the outer shells.
covalant bonds this bonds results when atoms share electrons. the stronger of the two bonds.
polar molecules when electrons are shared unequally
polar molecules are hydrophilic
non-polar molecules are hydrophobic
oxidation reaction when atoms lose electrons
reduction reaction when atoms gain electrons
ph scale measures the concentration of hydrogen ions in a solution.

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.
