Chemistry

TermDefinition
Atomic Number Number of protons in an atom nucleus
Protons A subatomic particle with a postive charge that is found in the nucleus. The mass of a proton is slightly less than a neutron.
Electrons The electron is a subatomic particle with a negative charge, the eletrons are a generation of the lepton family. The mass of the electron is 1/1836 of a proton.
Neutrons A subatomic particle with no electiric charge and is slightly more heavier then a proton (10/31319).
DNA DNA is a molecule that encodes the genetic instructions used in the development and functioning of all known living organisms and many viruses
Metalliods A metalloid is a chemical element that has properties in between, or is a mixture of.
Noble Gases The noble gases make a group of chemical elements with similar properties: under standard conditions, they are all odorless, colorless, monatomic gases with very low chemical reactivity.
Ions An Ion is an atom or molecule in which the total number of electrons is not equal to the total number of protons, giving the atom a net positive or negative electrical charge.
Chemical Reaction A chemical reaction is a process that leads to the transformation of one set of chemical substances to another.
Atomic Mass The atomic mass is the mass of an atomic particle, sub-atomic particle, or molecule. The protons and neutrons account for almost all of the mass of an atom.
Non-Metal Non-metals are the elements in groups 14-16 of the periodic table. Non-metals are not able to conduct electricity or heat very well.

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.
