λ=v/mh
Who said electrons move in a set path, and can only have certain energy levels
Neils Bohr
DeBroglie
Heisenberg
Schrödinger
Who created the uncertainty principle?
Heisenberg
DeBrogile
Dalton
Bohr
Which model was developed by Schrödinger?
Quantum mechanical model and atomic orbitals
Plum Pudding model
Nuclear model
What is Neils Bohr's contribution to the atomic theory?
Created the atomic theory
Created a model of the atom with electrons moving around the nucleus in a fixed orbits
Discovered that the proton had a positive charge
Discovered the electron
Why did Neils Bohr atomic model fail?
Because electrons don't exist
Electrons do not move around in fixed circular orbits
Electrons are actually positive
None of the above
What is the correct value for planks constant?
6.626 x10-34 Js-1
6.6 x10-36 J
6 x1038 Js-1
What was de Broglies main idea?
He believed electrons did not exist
He believed electrons, just like light particles, could act as waves
He developed atomic orbitals
What was Neils Bohr original idea of the atom?
A positively charged nucleus surrounded by electrons
A negatively charged nucleus surrounded by positive electrons
The nucleus holds all the protons, neutrons and electrons of an atom
Atomic Orbitals were developed by who?
Heisenberg
Schrödinger
Neils Bohr
