Question 10

to solve for a quantum of energy, use the equation

Answer 10

E=hv

Question 11

ephoton is equal to

Answer 11

the difference between the atoms initial state and its final state

Question 12

when the excited electron relaxes back to its ground state,

Answer 12

the energy is released as electromagnetic radiation

Question 13

bohrs model of a hydrogen states

Answer 13

1. electrons are in specified orbit; never in between
   2.when energy is put in, the electrons absorb the energy and become excited moving to a new energy level
2. when the excited electron relaxes and releases(emits) the energy, it will either fall back to its ground state or to a lower energy state
3. when the electrons fall to the lower energy level, it releases energy in the form of light color
4. perfectly explains hydrogen’s one electron
5. assumed to work out for all atoms
