Chem Chapter 7 Flashcards
A measure of the height of the crests or the depths of the trough of a wave
Amplitude
The total range of wavelengths of light that come from the sun
Electromagnetic spectrum
The lowest possible energy state for a given substance
Ground State
A specific shape that confines the position of an electron relative to the nucleus
Orbital
The constant the relates the energy of light to its frequency
Planck’s contant
Model of the atom in which electrons whirl around the nucleus in various paths called “orbitals”
Quantum mechanical model
A glass tube filled with small amounts of gas. Electrodes in the tube allows for the passages of electricity through the gas
Crooks Tube
The number of wave crests or (troughs) that pass a given point each second
Frequency
Atoms with the same number of protons but different numbers of neutrons
Isotops
A “particle of light”
Photon
One of the three particles that make up the atom. It is positively charged
Proton
Another name for Crook’s TubeCathode ray tube
Cathode ray tube
The total range of wavelengths of light that come from the sun
Electromagnetic Spectrum
A notation that lists the number of electrons that occupy each orbital in an atom
Electron Configurations
The lowest possible energy state for a given substance
Hertz
the process by which the abundance of one isotope elements are increased
Isotopic Enrichment
The total number of neutrons and protons
Mass Number
One of the three particles that make up the atoms. It is electrically neutral
Neutron
The Center of the atom that contains the neutrons and protons
Nucleus
A specific shape that confines the position of an electrons relative to to nuclear
Particle/Wave Duality Theory
The measures quantity in nature that does not change
Physical Constant
Another name for Rutherford model
Planetary Model
A physical quantity (such as energy) cannot have any value, bit its restricted to have only discrete values
Quantum Assumptions
The cells on the eye’s retina that detect low levels of light
Rods
A device that analyzes light emitted or absorbed by a substance
Spectrometer
The process by which individual wavelengths of light emitted by a substance are analyzed
Spectroscopy
The cells on the eyes retina that detect different energies of light
Cone
