100
This rule states that electrons will fill empty orbitals singly before pairing up.
What is Hund's Rule?
100
This appears in all materials and is the tendency of a material to oppose an applied magnetic field (i.e, to be repelled by a magnetic field)
what is diamagnetic
100
Known for creating the cathode ray tube
Who is william crookes
100
Regions where there is a very high probability of finding an electron.
What is an Orbital?
200
This rule states that electrons fill orbitals starting from the lowest available energy level and move to higher levels only when the lower ones are full
What is The Aufbau Principle
200
Said that All matter is made up of four basic substances earth, water, air and fire
Who is Aristotle?
200
Schrodinger created this to help us understand the energy and position of electrons
What is Schrodinger's equation?
300
This rule states each orbital can hold a maximum of two electrons, and these electrons must have opposite spins.
What is the Pauli Exclusion Principle
300
The ernest rutherford model of the atom
300
This number describes the shape of atomic orbitals
what is the secondary quantum number?
400
This principle says You can know where an electron is or how fast it’s moving, but not both at once.
What is the Heisenberg's Uncertainty principle
400
Used the gold foil experiment to prove JJ Thompsons theory of the atom
Who is ernest rutherford?
400
This sublevel is made of 7 degenerate orbitals and can hold a maximum of 14 total electrons
What is the f orbital?
500
Used a mass spectrometer to collect evidence suggesting that atoms of the same element have different masses
Who is francis ashton
500
What is the concept that describes how light exhibits particle-like properties, as shown in the photoelectric effect, and how particles, such as electrons, can also behave like standing waves?
What is wave particle duality?
