Term | Definition |
Electromagnetic Radiation | Energy that exhibits wavelike behavior and travels through space at the speed of light in a vacuum |
Wavelength | The distance between two consecutive peaks or troughs in a wave |
Frequency | The number of waves (cycles) per second that pass a given pint in space |
Planck's constant | The constant relating the change in energy for a system to the frequency of the electromagnetic radiation absorbed or emitted |
Photon | A quantum of electromagnetic radiation |
Continuous Spectrum | A spectrum that exhibits all the wavelengths of visible light |
Line Spectrum | A spectrum showing only certain discrete wavelengths |
Ground State | The lowest possible energy state of an atom or molecule |
Orbital | A specific wave function for an electron in an atom. The square of this function gives the probability distribution for the electron. |
Principle quantum number (n) | The quantum number relating to the size and energy of an orbital; it can have any positive integer value |
Angular momentum quantum number (l) | The quantum number relating to the shape of an atomic orbital, which can assume any integral value from 0 to n-1 for each value of n. |
Magnetic quantum number (ml) | The quantum number relating to the orientation of an orbital in space relative to the other orbitals with the same (l) quantum number. It can have integral values between (l) and -(l) including 0. |
Electron spin quantum number | A quantum number representing one of the two possible values for the electron spin; either +1/2 or -1/2 |
