1924393142electronsa smeared out cloud that surrounds the nucleus and gives the atom it's apparent size - has an electrical charge that is precisely opposite that of a proton so it has a negative charge (-1)32
1924393143electrical chargeproperties of an atom depend on this. It is a fundamental physical property that describes how strongly an object will interact with electromagnetic fields. - Is the basic unit of positive charge (+1)33

1924457960IonizationProcess of stripping electron from atoms Example: ionization turns what was once water into a hot gas consisting of freely moving electrons in positively charged ions of hydrogen and oxygen46
1924457961PlasmaType of hot gas in which atoms have become ionized Sometimes referred to as the fourth phase of matter because of its charged particles interaction with light47

1951419269Law One of Thermal RadiationEach square meter of a hot objects surface emits more light at all wavelengths. Example: when a poker is still relatively cool it emits only infrared light which we cannot see. As it gets hot it begins to glow with visible light and includes more brightly as it gets hotter57
1951419270Law two of thermal radiationHotter objects emit photons with a higher average energy , which means a shorter average Example: the color of a hot poker demonstrates this.58
1951419271The Doppler effectIf an object is moving toward us the light waves bunch up between us and the object so its entire spectrum is shifted to shorter wavelengths.59
1951419272BlueshiftA Doppler shift in which spectral features are shifted to shorter wavelengths, observed when an object is moving toward the observer.60
