|---|---|---|---|---|---|
| Atom | Fundamental building block of all materials; it consists of a cluster of protons and neutrons surrounded by a cloud electrons
🗑
|
||||
| Atomic Number | the number of protons in a nucleus; the atomic number determines what type of atom it is
🗑
|
||||
| Compound | A pure substance that is made up of two or more different types of atoms chemically joined
🗑
|
||||
| Crystal-Lattice | A grid-like structure of atoms or ions where particle is bonded to all of its neighboring atos
🗑
|
||||
| Element | a substance made up of only one type of atom
🗑
|
||||
| Isotopes | atoms that have the same number of protons but a different number of neutrons in their nucleus
🗑
|
||||
| Anion | Negatively charged ion
🗑
|
||||
| Cation | Positively charged ion
🗑
|
||||
| Ion | an atom that has lost or gained electrons and therefore has an electric charge
🗑
|
||||
| Ionic Bond | a bond between a cation and an anion due to electrostatic attraction of their opposite charge
🗑
|
||||
| Alpha Decay | a nuclear reaction in which a nucleus ejects an alpha particle
🗑
|
||||
| Alpha Particle | a particle made up of two protons and two neutrons, making it identical to a helium nucleus
🗑
|
||||
| Beta Decay | a form of nuclear reaction in which a beta particle is ejected
🗑
|
||||
| Beta Particle | a small, negatively charged particle that can be ejected from a nucleus during a nuclear reaction; it is identical to an electron
🗑
|
||||
| Nuclear decay | when a nucleus undergoes a nuclear reaction and emits radiation
🗑
|
||||
| Half-Life | the time it take for half the nuclei to decay
🗑
|
||||
| Radioisotope | an isotope with a nucleus that may undergo a nuclear reaction
🗑
|
||||
| Transmutation | one element transforming into another
🗑
