Arrangement of electrons in the atom CH3 Flashcards
Who was the Danish who provided insight into the arrangement of the atom?
Niels Bohr
Continuous spectrum
A light passed through rough prism, the light is broken up into a array of colours.
Emission line spectrum?
hydrogen discharge is passed through rough prism.
Quantun energy
A fixed amount of energy.
Bohr’s theory
Electrons orbit the nucleus along fixed paths called orbits or energy levels.
Energy level
The fixed amount of energy value that an electron in an atom may have.
Ground state
A n atom is one which the elections occupy the lowest available energy levels.
Excited state
An atom is one in which the electron occupy the higher energy level than those available.
Atomic Absorption Spectrometry (AAS)
?
Uses of AAS
Measuring the concentration of lead in the blood.
Energy sublevel
Energy levels that are very close together.
Sublevel label
S,P,D,F
Wave Nature
Idea that a particles can behave like a wave is often referred to as wave particle duality.
Heisenberg’s uncertainty principle
That it’s impossible to measure at the same time both velocity and the position of the atom.
Bohr’s limitations
Does not work with atoms with more then one electron, didn’t take into account wave motion and sublevels.
