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 |
