Electron Configuration Flashcards
How fast do electromagnetic waves(aka radio-waves, x-rays, and microwaves) travel?
Speed of Light
Define: Photon and Orbital
Photon: particle of a quantum of light
Orbital: pattern of electrons around an atom
Define: Wavelength and Frequency
Wavelength: length of a complete wave
Frequency: number of crest passages per unit of time
Energy is directly related to ___.
Wavelength is inversely related to ___.
Frequency multiplied by wavelength is equal to ___.
- Wavelength
- Frequency
- Speed of light
If wave “b” has a higher wavelength than wave “a”. Then “b”s energy and frequency is ___ than wave “a”.
Higher
Unit for wavelengths(when in equations) and frequency are:
- nm
- hz
What letter represents an energy level?
n(n=1 being the closest to the nucleus)
Define ground state and excited state:
Ground state: electron moving to the lowest energy state(emits energy to do so)
Excited state: electron moving to the highest energy state(absorbs energy to do so)
Amount of total electrons/orbitals(plus which orbitals) for n=1,n=2,n=3,n=4,etc
- n=1: 2 electrons and 1 orbital
- n=2: 8 electrons and 3 orbitals
- n=3: 18 electrons and 5 orbitals
- n=4: 32 electrons and 7 orbitals
Definitions for photon and wavelength?
- the distance from the trough of one wave to the rough of the next
- a discrete particle of energy
Instrument that combines a prism and a telescope?
grism
Planck’s hypothesis states that energy per photon is ___ proportional to the wavelength.
inversely
c=
E=
m=
λ=
- hλ
- hf
- 1*10^-9
- wavelength
De Broglie described light as having duel properties. It cant act as both a ___ and a ___.
- wave
- particle
What is the “atomic fingerprint” and why does each element have their own unique fingerprint?
- the specific colors of light it emits
- because each element emit’s a different amount of energy.
