4 the arrangement of electrons of an atom in its ground state into various orbitals around the nuclei of atoms
5 the specific energies an electron in an atom or other system can have
6 one of the Group B elements in which the highest occupied s sub level and a nearby d sub level generally contain electrons
7 a mathematical expression describing the probability of finding an electron at various locations; usually represented by the region of space around the nucleus where there is a high probability of finding an electron
12 an atomic orbital may describe at most two electrons, each with opposite spin direction
13 the distance between adjacent crests of a wave
14 the pattern formed when light passes through a prism or distraction grating to separate it into different frequencies of light it contains
15 when the elements are arranged in order of increasing atomic number, there is a periodic repetition of their physical and chemical properties
16 the rule that electrons occupy the orbitals of lowest energy first
17 a horizontal row of elements in the periodic table
18 a number used to calculate the radiant energy (E) absorbed or emitted by a body based on the frequency of radiation
19 the lowest possible energy of an atom described by quantum mechanics
1 a quantum of light; a discrete bundle of electromagnetic energy that interacts with matter similar to particles
2 wavelengths of visible light that are separated when a beam of light passes through a prism; range of wavelengths of electromagnetic radiation
3 the amount of energy needed to move an electron from one energy level to another
4 energy waves that travel in a vacuum at a speed of 2.988 X 10^8 m/s; includes radio waves, microwaves, infrared waves, visible light, ultraviolet waves, X-rays, and gamma rays
8 electrons occupy orbitals of the same energy in a way that makes the number or electrons with the same spin direction as large as possible
9 the height of a wave's crest
10 the number of wave cycles that pass a given point per unit of time; frequency and wavelength are obversely proportional to each other
11 a quantum mechanical property of electrons that may be thought of as clockwise or counterclockwise
