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 |
