Parts of an Atom
| Question | Answer |
|---|---|
| Atom | The smallest unit of all matter that maintains properties of certain elements |
| Proton | Positively charged subatomic particles in the nucleus |
| Nuetron | Subatomic particles in the nucleus with no charge |
| Electron | Negatively Charges subatomic particles found outside the nucleus |
| Nucleus | An atoms central region, made up of protons and electrons |
| Orbital | Also called an electron cloud, the region around the nucleus where electrons can be found |
| Isotope | An atom of an element that has a different number of neutrons |
| Atomic Mass | Sum of the protons and neutrons found within the nucleus |
| Atomic Number | The number of protons found in the nucleus |
| Gravitational Force | Force of the pull of objects on each other |
| Electromagnetic Force | Force of objects of different charges attracting eachother |
| Strong Force | Force of the Neutrons pulling the protons together |
| Weak Force | The force of a neutron changing into a proton in unstable atoms |
| Subatomic | Anything smaller then an atom |
| Metals | Region of the Periodic Table, these elements are malleable, have a high density, usually shiny, and are good at conducting electricity |
| Nonmetals | Region of the periodic table, these elements are brittle, have a low density, usually are dull, and have a low melting temperature |
| Metalliods | Region of the periodic table, these elements have properties of both metals and non metals |
| Valence Electron | Electrons that are found in the outermost orbital, the groups of the periodic table always have the same amount |
