EL: Atomic Absorption

Question 1

How many types of line spectra are there and what are they?

Answer 1

2 ; Absorption and Emission Spectres

Question 2

Describe the difference between how the two line spectra are visualised.

Answer 2

Absorption spectra = black series on a coloured spectrum
Emission spectra = coloured series on a black background.

Question 3

What must be true for EM radiation to pass through an element?

Answer 3

The element must be in a gaseous state.

Question 4

What do electrons absorb and how does that relate to energy in shells?

Answer 4

Electrons absorb specific frequencies that correspond to the difference in energy between shells.

Question 5

What do the black series in the line spectra actually show?

Answer 5

They show the frequencies ,which are now missing, at which electrons have absorbed energy when radiation passed through.
