To move an electron from the ground state up (to excite it) what has to happen?
The atom has to absorb energy from collisions with other atoms or from a photon of light
Atom that absorbed a photon of light is what
An excited atom
Electron can be moved to a wider orbit or higher energy state by absorbing energy a very precise amount
True
For a photon of light to be absorbed by an electron what has to be true ?
It has to have the exact right amount of energy it will pass by if it has too little or too much
How much energy in a hydrogen atom does it take to move an electron from ground to the second level?
A specific amount and more energy to move to the third level and more to 4th
Only a photon of the correct wavelength will excite the atom
True
Only a photon of the correct color will excite the atom
True
Once an electron is at the higher energy state/ larger orbit it immediately jumps back down
It releases the excess energy as a photon of exactly the same energy it absorbed
An electron can stop briefly at different levels/ orbits to release the energy
The energy it releases will be less as it goes
The photons an atom Elmira during this process are completely unique
Spectroscopy identifies through the spectral lines what the chemical is and also environmental factors such as temperature and density of atoms
