Electromagnetic Waves
The condition of an atom whose electrons are all at the lowest possible energy levels.
What is ground state?
A measure of the size of an atom, usually the mean or typical distance from the center of the nucleus to the outermost isolated electron.
What is atomic radius?
The number of electrons allowed in the p-sub level.
What is six?
Periodic Table group whose ground state electron configurations end in s1
What are alkali metals?
The least reactive group on the periodic table.
What are the noble gases?
Color of light with the highest energy.
What is violet?
a row of chemical elements.
What is a period?
in the ground state of an atom or ion, electrons fill subshells of the lowest available energy, then they fill subshells of higher energy.
What is the Aufbau Principle?
Periodic Table group whose ground state electron configurations end in p5
What are halogens?
15 metallic chemical elements with atomic numbers 57–71. These elements, along with the chemically similar elements scandium and yttrium, are often collectively known as the rare-earth elements or rare-earth metals
What are the lanthanides?
Color of light with the longest wavelength?
What is red.
What are the noble gases?
every orbital in a subshell is singly occupied with one electron before any one orbital is doubly occupied, and all electrons in singly occupied orbitals have the same spin.
What is Hund's Rule?
Periodic table group whose ground state electron configurations end in s2.
What are alkaline earth metals?
The term for an electron at a higher energy level than its ground state.
What is excited?
the rate at which a vibration occurs that constitutes a wave, either in a material (as in sound waves), or in an electromagnetic field (as in radio waves and light), usually measured per second.
What is frequency?
The tendency for an atom of a given chemical element to attract shared electrons when forming a chemical bond.
What is electronegativity?
it is impossible for two electrons of a poly-electron atom to have the same values of the four quantum numbers: n, the principal quantum number; ℓ, the azimuthal quantum number; mℓ, the magnetic quantum number; and ms, the spin quantum number.
Pauli Exclusion Principle
The most reactive group of nonmetals on the periodic table.
What are halogens?
What are the actinides?
an elementary particle that is a quantum of the electromagnetic field, including electromagnetic radiation such as light and radio waves, and the force carrier for the electromagnetic force.
What is a photon?
the minimum energy required to remove the most loosely bound electron of an isolated gaseous atom, positive ion, or molecule.
What is ionization energy?
What is an orbital?
an element whose atom has a partially filled d sub-shell, or which can give rise to cations with an incomplete d sub-shell
What are transition metals?
The complete electron configuration for Uranium.
