Bohr's Study Of Spectra Flashcards
Who was the first to provide an insight into the arrangement of electrons in the atom?
Niels Bohr
What was Niels Bohr’s contribution to science?
He provided an insight into the arrangement of electrons in the atom
What happens when white light is passed through a glass prism?
The white light is broken up into an array of colours
What must white light be passed through to produce an array of colours?
A glass prism
When white light is passed through a glass prism an array of colours is produced, what is this array of colours called?
A spectrum
What are the two types of spectrums?
Continuous spectrum
Line spectrum
Give an example of a continuous spectrum.
A rainbow
How is a rainbow formed?
When rain acts as tiny prisms and separates sunlight into its colours
What is a hydrogen discharge tube?
A glass tube filled with hydrogen gas at low pressure through which an electric current is passed
What was produced when light from a hydrogen discharge tube was passed through a glass prism?
A series of narrow coloured lines
What is the name given to the series of narrow coloured lines produced when light from a hydrogen discharge tube is passed through a glass prism?
A line spectrum
What is a line spectrum more accurately called?
An emission line spectrum
Why is it more accurate to call a line spectrum an emission line specttrum?
Since the light is emitted when an electric current is passed through hydrogen
How can emission line spectra be used by chemists to detect its presence?
This is because each element has its own unique emission line spectrum
