One way the modern atomic model differs from thomson's atomic model is that electrons are no longer scattere'd throughout an atom's positive matter like chocolate chips in cookie dough. instead, each electron is outside of the nucleus occupying a specific

The answer is: energy level.

According to the Bohr model of the atom:  

1. Energy levels of electrons are discrete (certain discrete values of energy)., that is why hydrogen shows discrete, bright, colored lines.  

2. Electrons orbit the nucleus in orbits that have a set size and energy.  

3. Electrons can jump from one energy level to another, absorbing or emitting electromagnetic radiation with a frequency ν (energy difference of the levels).
