Term | Definition |
Electromagnetic Radiation | form of energy that has wavelike behavior as it travels through spave |
Electromagnetic Spectrum | All the forms of electromagnetic radiation |
Wavelength | distance between corresponding points on adjacent waves |
Frequency | (v) number of waves that pass a given point in a specific time, usually one second (described as waves/second called hertz) |
photoelectric effect | emission of electrons from a metal when light shines on the metal |
quatntum | energy that is the minimum quantity of energy that can be lost or gained by an atom (E is the energy in Joules) |
Planck's constant | h=6.626x10-34th Jxs |
electromagnetic radiation equation | c(speed)= /\(wavelength)x v (frequency) |
Photon | particle of electromagnetic radiation having zero mass and carrying a quantum energy |
ground state | lowest energy state of an atom |
excited state | atom has a higher potential energy than it has at ground state |
continuous spectrum | emission of continuous range of frequencies of electromagnetic radiation |
Niels Bohr | proposed a hydrogen atom model that linked the atoms electron to photon emission (Plum pudding!!) |
Heisenberg uncertainty principle | states that its impossible to determine simultaneously both the position and velocity of an electron or any other particle |
Quantum Theory | describes mathematically the wave properties of electrons and other very small particles |
orbital | three dimensional region around the nucleus that holds electrons |
