6th Grade Chemistry

QuestionAnswer
element a pure substance that cannot be broken down by any means; examples include carbon, oxygen, hydrogen
matter anything that has mass and volume
compound two or more elements chemically combined
physical property a characteristic that can be observed without changing what the substance is made of. Ex. The bread is soft.
chemical property a characteristic that you observe when a substance REACTS with another substance. Ex. Silver reacts with oxygen (tarnishes).
physical changes a change that alters the appearance of a substance, but does not affect what it is made of. Ex. Dry ice sublimating.
chemical changes a change in matter that produces a new substance. Ex. Burning toast.
mass the amount of matter in an object
volume the amount of space an object takes up
density the amount of matter in a given space. d=mass divided by volume
precipitate a solid that forms as the result of a chemical reaction between two liquids
sublimation the phase change from a solid to a gas; dry ice does this
reactivity the ability of a substance to react with another substance to form something new
condensation the phase change that occurs when a gas cools down enough to change to a liquid; clouds are formed this way
vaporization phase change from a liquid to a gas; molecules speed up and move further apart
evaporation phase change from a liquid to a gas; occurs on the surface of a liquid
organic compounds that contain carbon; compounds that come from once living organisms
inorganic compounds that come from minerals; compounds that come from non-living material
periodic table a systematic way to organize elements according to common physical and chemical properties
ductility the ability of a substance to be stretched into a very thin wire such as gold; this is a PHYSICAL PROPERTY
malleability the ability of a substance to be pounded into thin sheets without shattering such as aluminum; this is a PHYSICAL PROPERTY
conductivity the ability of a substance to allow heat or electricity to travel through it easily such as copper; this is a PHYSICAL PROPERTY
metals a group of shiny, strong, & solid elements that are good conductors of electricity and heat and are usually malleable & ductile
non-metals a group of elements that are either weak, brittle solids or gases that are not conductors, not malleable, and not ductile
metalloids a group of elements that have properties of both metals and non-metals
boiling point the temperature at which a substance changes state from a liquid to a gas; ex. water boils at 100 degrees C and this is a PHYSICAL PROPERTY
melting point the temperature at which a substance changes state from a solid to a liquid; ex. water melts 0 degrees C and this is a PHYSICAL PROPERTY
luster the state or quality of shining by reflecting light
