S1.3 Electron Configuration Flashcards
(11 cards)
What is the electromagnetic spectrum?
The range of wavelengths or frequencies of electromagnetic radiation
What is the a continuous sceptrum?
A continuous sceptrum is a emissions spectrum that consists of all wavelengths within a range
What is a emissions spectrum?
A spectrum of electromagnetic radiation emitted from a source
What is a line (emission line) spectrum?
a emissions spectrum that consists of only a few wavelength within a range

What two things does the hydrogen emissions spectrum show?
Electrons exist in discrete energy levels
Energy levels get closer as we go out from the nucleus
What two things does the hydrogen emissions spectrum show?

What happens to the electron for the light to be released?
Energy is absorbed due to ionisation then energy is released and colour depends on the amount released due to electron transition
What is the series of light rays in visible light called? And to which n= is it too?
The Balmer series and n=2
What do the lines do in the line emissions spectrum at high energy levels?
Converge
