chemistry 2

VSEPR based on an arrangement that minimizes the repulsion of shared and unshared pairs of electrons around the central atom
covalent bond a chemical bond that results from the sharing of valence electrons
physical properties a characteristic of matter than can be observed or measured without changing the samples composition
triple bond when three pairs of electrons are shared
double bond when two pairs of electrons are shared
single bond when one pair of electrons are shared
polarity the unequal amount between bonds
anion an ion that has a negative charge
cation an ion that has a positive charge
ionic compound compounds that contain ionic bonds
ions an atom or bonded group of atoms with a positive or negative charge
intermolecular forces the attraction that holds particles together in ionic, covalent, and metallic bonds
intramolecular forces the forces that do not account for all attractions between particles
ionic bond the electrostatic force that holds oppositely charged particles together in an ionic compound
covalent compound the linkage between atoms or radicals of a chemical bond
binary compound chemical substances made from just two chemical elements
diatomic molecules a molecule composed of two atoms
superscript the number used to represent the number of isotopes
subscript indicates the number of the preceding element
covalent compounds compounds that contain covalent bonds
polyatomic ions an ion made up of two or more atoms bonded together that acts as a single unit with a net charge
transition metals an element in groups 3-12 contained in the d-block
percent composition the percent by mass f each element in a compound
mole the SI base unit used to measure the amount of a substance
avogadros number 6.02*10^23
hydrate a compound that has a specific number of water molecules bonded to its atoms
empirical formula the formula that shows the smallest whole-number mole ratio of the elements of a compound
representative particle any kind of particle
molar mass the mass in grams of one mole of any pure substance
percent composition the percent by mass of each element in a compound
molecular formula a formula that specifies the actual number of atoms of each element in one molecule of a substance
physical change a change which alters a substance without changing its composition
chemical change a process that involves one or more substances changing into new substances
coefficient the number that appears before the reactant in an equation
conservation of mass the mass of an object or collection of objects never changes nor can they rearrange themselves
balanced reaction the same number of products and reactants is the same on both sides
chemical reaction the observation that the product has different properties than the reactants
synthesis two or more substances react to yield a single product
decomposition a single compound breaks down into two or more elements or new compounds
single replacements the atoms of an element replace the atoms of another element
double replacement the exchange of ions between two compounds and products either a precipitate, a gas, or water
aqueous solution a solution in which the solvent is water
precipitate a solid produced during a chemical reaction in a solution
combustion a substance reacts with oxygen releasing energy in the form of heat or light

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.
