Matter, Phases, Atom

Phases, Phase Changes, Definition of Matter, Atom, Periodic Table basics

QuestionAnswer
Proton charge and location positive charge, inside nucleus.
Neutron charge and location neutral charge, inside nucleus.
Electron charge and location negative charge, outside nucleus/electron cloud
Element 94 naturally occurring on earth; can be found as a square on the periodic table
Atomic Number tells you the number of protons and electrons
Atomic Weight (mass) The weight of the protons and neutrons in the nucleus (electrons have almost no weight)
Chemical Symbol Short way of writing the elements name. (1st letter always capitalized, rest lower case)
Matter Anything that has mass AND volume
Non-matter Anything energy. (Heat, sound, light)
Temperature the vibration of the particles, temperature can stop changing and stay the same.
Heat the vibration of the particles, heat never stop moving.
Solid Definite volume and definite shape.
Solids move.... Molecules move in place but cannot overcome the attraction between the molecules.
Liquid Definite volume, but no definite shape. They take the shape of their container.
Liquids move.... molecules are able to slide over each other but particles are still attracted to each other
Gas No definite shape or no definite volume
Gas move.... molecules have very little attraction to other particles and are highly energized.
Melting Solid to a liquid. Heat added
Freezing Liquid to a solid. Heat is removed
Evaporation Liquid to a gas. Heat is added
Condensation Gas to a liquid. Heat is removed
Sublimation Solid to a gas. Heat is added
Endothermic Heat is added
Exothermic Heat is removed
What happens to temperature during a phase change? Temperature stays the same
What happens to temperature during the phases of matter? Temperature goes up or down
What are the phases of matter? solid, liquid, gas
What are the phase changes of matter? Melting, Freezing, Evaporation, Condensation
