Learning About The Bohr Model

"Energy Levels" of A Ladder

Explaining It Better

Some features of the Bohr Model can be compared with a ladder.  The steps, also called rungs, on a ladder can be represented as energy levels.  When a person climbs the ladder, that shows higher levels of energy.  This means that the rungs are the only places that a person can be located at...or otherwise, stand on or be able to get on the ladder. 
 
Let's say that only one person can stand on a rung on the ladder.  A ladder that has 14 rungs on it can have as many as 14 people, but no more than that.  Now, let's say that there are only 5 people on the ladder. 
 
This means that those 5 people can be anywhere on the ladder, and there is still more room for more people.  Just as long as the people still follow the rule of only having one person on a rung at a time. 
 
The lowest energy level that there could be would have the 5 lowest rungs that are being used.  No one could move any lower.
 

Questions
 
*How do electrons gain or lose energy?
