simple chemistry

QuestionAnswer
Chemistry science that deals with composition of matter
Element substance from wich all matter is made of
Atom Fundimental unit that makes up chemical elements
Proton Positively charged atom
neutron nuetral no charge atom
electron negatively charged atom
neucleous center of Atom
atomic number number of protons and electrons present in nuecleus or around nucleus of each of it's atoms
orbital circulates around atom
energy levels defined by distance from the nucleus
1st energy level closest to necleus composed of one orbital max of two electrons
2nd energy level farthest away can have up to four orbits possible 8 electrons
Nonmetal outer most energy level must have more than 4 electrons but less than eight electrons
metal outer most shell must have less than 4 electrons.
Molecules simply a combination of two or more atoms
Molecule can be made of like atoms
Molecule most often made of 2 or more different atoms
compounds molecules formed by union of 2 or more atoms
simple made of few elements
complex made of many elements
water most abundant compound in body
mixture blends of two or more substances
types of mixtures solution, suspension, colloidal
solution mixture remain evenly distributed, like sugar in tea
suspension mixture solvent settles out unless constantly shaken like salad dressing
colloidal suspension mixture particles do not disolve like fruit in jello
dissolving substance is the solvent, like water in koolaid
solute substance that is dissolved, like salt, sugar, koolaid
neutralized equal number of protons and electrons
Ionic Bond Opposites attract. Produce compound when cling together
Covalent Bond Sharing. sharing of electrons between atoms.
acid chemical substance capable of donating a hydrogen ION to another substance
Base chemical substance containg a hydrogen ION that can accept a hydrogen ION
a reaction between an acid and a salt produces what? Salt
buffers chemicals that maintain homeostasis in body
we need these compounds to sustain life organic compounds
organic compounds all chemical compounds that sustain life
organic compounds must contain these to be classified carbon, hydrogen, oxygen
Large Complex molecules consist of organic compounds
Lrge compound molecules formed from simple molecules called building blocks

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.
