3. Atomic emission spectrum
As you recall from the section you’ve just read
-Hydrogen emission spectra is discontinuous ( made up of select
frequencies of light)
But why are elements atomic emission spectra discontinuous
rather than continuous ?
A young physicist named Nicholas Bohr proposed a quantum
model for hydrogen that seemed to answer this question

15. • Unlike Bohr’s model , this one even makes an attempt to describe
• and electron’s path around the nucleus
• A three dimensional region around the nucleus call an atomic
orbital describes the elctron’s probable location
• Describe loosely before with electron cloud model in which
the electron will spend about 90% of its time near the positively
charged nucleus
