Matter
The three states of matter.
What are solids, liquids, and gasses?
Smallest particle of an element that has all the properties of that element.
What is an atom?
Kind of change during which compounds are formed. (Example: Rust)
Point at which matter changes from a solid to a liquid.
What is melting point?
Substance in which a solute is dissolved.
What is a solvent?
Matter that has no definite shape or volume.
What are gasses?
Equal to the number of protons in an atom; found on Periodic Table.
Group of symbols that represent a compound?
What is a chemical formula?
Point at which a liquid changes to a gas.
What is boiling point?
The amount of solute that can be dissolved in an amount of solvent.
What is solubility?
Matter that has a definite volume but no definite shape.
What are liquids?
Region around the nucleus of an atom occupied by electrons.
What is an Electron Cloud?
Formed when 2 or more atoms bond by sharing electrons.
What is a molecule?
Point at which a liquid changes to a solid.
What is freezing point?
When all solute a solution can hold is dissolved.
What is a saturated solution?
Matter in which molecules are packed tightly together and move only slightly.
What are solids?
Elements with 5 or more electrons in the outer energy level.
What are metals?
Charged particle resulting when an atom loses one or more electrons.
What is an ion?
A change of matter from a vapor to a liquid.
What is condensation?
Mixture in which substances are not spread out evenly. (Example: trail mix)
What is heterogeneous?
What is viscosity?
The simplest element.
A common compound with 2 hydrogen and 2 oxygen atoms.
What is hydrogen peroxide?
A change of matter from liquid to gas without boiling.
What is evaporation?
An insoluble solid in a liquid.
What is suspension?
