Module #7: Atomic Structure Flashcards
What are the three statements about electrical charge?
Like charges repel one another, Opposite charges attract each other, and Every substance has electrical charges
Mass number
The total number of neutrons and protons in an atom
Isotopes
Atoms with the same number of protons but different numbers of neutrons
Particle/Wave duality theory
The theory that light sometimes behaves as a particle and sometimes behaves as a wave
Wavelength
The distance between the crests (or troughs) of a wave
Amplitude
A measure of the night of the crest or the death of the trough of a wave
Physical Constant
A measurable quantity in nature that does not change
Frequency
The number of crests (or troughs) that pass a given point each second
F = what over what?
F = c/lambda
Finish the statement: as a light wave’s frequency increases…
It’s energy increases
Finish the statement: as a light wave’s frequency decreases…
It’s energy decreases
Wavelength is inverse to what?
Frequency
Ground state
The lowest possible energy state for a given substance
