TermDefinition
matter physical substance in general occupies space and possesses rest mass, especially as distinct from energy.
atoms An atom is the smallest unit of matter that defines the chemical elements. Every solid, liquid, gas. is made up of protons and nutrons which creates the nucleus.
molecules a group of atoms bonded together, representing the smallest fundamental unit of a chemical compound that can take part in a chemical reaction.
Elements 1 or more same type of atom Example: O2
Compound 2 or more different types of atoms bonded together. Example: NaCi
Pure Substance Pure Substance: made up of one types of matter (can be an Element or Compound). cant be seperated physically (must be chemically) Example: H20
Mixture Mixture: made up of multiple types of matter, more than 1 dont bond together can be seperated by physically = sorting filtering and distilletion. Example: AuAs, Cu 14k
Heterogeneous Mixture Heterogeneous Mixture: a mixture where the particles are not evenly distributed
Homogeneous Mixture Homogeneous Mixture: a mixture where the particles are evenly distributed
chemical formula the formula that the chemical is.
colloid a mixture containg mid-size particles that do not settle out
particle size the size of the particle taking up space
settling out To cause (a liquid) to become clear by forming a sediment.
solution a mixture containg atoms, ions, or molecules that fully dissolved.
suspension a mixture containg particles that settle out if left undisturbed
tyndall effect dispersed colloid particles scatter lights, allowing us to see between colloids and solutions.
physical property- any property that is measurable whose value describes a state of a physical system.
chemical property- a property or characteristic of a substance that is observed during a reaction in which the chemical composition or identity of the substance is changed
flammability Flammability is the ability of a substance to burn or ignite, causing fire or combustion
reactivity the state or power of being reactive or the degree to which a thing is reactive. the extent to which a nuclear reactor deviates from a steady state
metal a solid material that is typically hard, shiny, malleable, fusible, and ductile, with good electrical and thermal conductivity
non-metal an element or substance that is not a metal.
metalloid an element whose properties are intermediate between those of metals and solid nonmetals.
ATOMIC NUMBER The number of protons in the nucleus of an atom
ATOMIC WEIGHT Another term for atomic mass.
ELECTRON AFFINITY Change in energy of a neutral atom when an electron are added to the atom to form a negative ion.
ELECTRONEGATIVITY A measure of the tendency of an atom to attract a bonding pair of electrons.
ATOMIC RADIUS A chemical element is a measure of the size of its atoms, usually the mean or typical distance from the center of the nucleus to the boundary of the surrounding cloud of electrons.
METALLIC CHARACTER The level of reactivity of a metal. Metals tend to lose electrons in chemical reactions, as indicated by their low ionization energies
TYPES OF CHEMICAL BONDS FORMED Various types of atoms are attracted to each other and come together in a bond
VALENCE ELECTRONS An electron that is associated with an atom, and that can participate in the formation of a chemical bond
IONIZATION ENERGY An atom or molecule describes the minimum amount of energy required to remove an electron from the atom or molecule in the gaseous state.
MELTING POINT T temperature at which a given solid will melt
NUMBER OF BONDS FORMED The bond formed by the sharing of a pair of electrons by two atoms. Origin of covalent bond Expand.

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.
