The Study Of The Atoms Part 1
Term | Definition |
---|---|
Elements | Pure substance made of only one type of atom |
Atom | Smallest particle of matter |
Solid | has the least amount of energy particles are arranged in pattern particles vibrate |
liquid | energy between solid and gas particles slide past one another |
gas | Has the most energy particles are random free and fast movement |
Malleable | Ability of a metal to be flattened |
Ductile | Ability of a metal to be drawn out into aa thin wire |
Luster | Ability of a metal to shine |
Density | The amount of mass in a particular volume |
Brittle | Breaks easily characteristics of nonmetal |
Metalloid | Group of elements that show characteristics of both metals and nonmetals |
Condensation | change in the state of matter When a substance goes from gas to a liquid |
Sublimation | change in the state of matter when a substance goes from a solid to a gas |
Deposition | change in the state of matter when a substance goes from a gas to a solid |
Protons | subatomics particles that is a positive and found inside a nucleus found by the atomic number |
Electrons | Subatomic particles that are found outside of the nucleus found by the atomic number |
Neutron | subatomic particles that is a neutral/no and found in the nucleus found by rounding the atomic mass and subtracting the atomic number |
