Scientists
The experiments by this English physicist were the first to provide evidence of the electron's evidence.
Who is J.J. Thomson?/Who is Thomson?
According to this outdated model, since improved by quantum theory, electrons orbit the nucleus.
What is the Bohr-Rutherford model?
There are this many quantum numbers.
What is 4?
The maximum amount of electrons that can occupy the 6s, 6p, 5d, and 4f sublevels in total.
What is 32?
A shortened way to express an atom's electron configuration.
What is noble gas configuration?
This physicist discovered that energy comes in small, fixed packets called quanta.
Who is Max Planck?/Who is Planck?
A mathematical description of an orbital in an atom where an electron of certain energy is likely to be found.
What is the wave function?
When the l = 3, this is the number of possible values of the ml value.
What is 7?
These orbitals are said to be shaped like 4-leaf clovers.
What are d orbitals?
This asserts that the electron configuration is built up by adding electrons and filling up the lowest energy orbitals first before moving on to the higher energy ones.
What is the Aufbau principle?
This scientist proposed the Uncertainty Principle.
Who is Werner Heisenberg?/Who is Heisenberg?
This model's two main ideas are that the exact position of an electron cannot be determined and that electrons can transition to different orbitals by absorbing or emitting quanta of energy.
What is the quantum mechanical model?
This determines the size and energy of an atomic orbital, in other words known as a shell.
What is the Principal Quantum Number (n)?
This mathematical equation is used to predict the shape of each of the 4 atomic orbital types.
What is Schrodinger's wave equation?
An atom's real electron configuration may be different than the expected one for this reason.
What is stability?
The scientist credited with the idea that the electron has both particle and wave-like properties.
Who is Louis De Broglie?/Who is De Broglie?
The specific name for the model which showed orbitals with different shapes.
What is the electron cloud model?
This figure is limited to the values +1/2 and -1/2, representing a spin-up and spin-down electron, respectively.
What is the Spin Quantum Number (ms)?
This displays an upside-down staircase which shows how electrons are added to each orbital.
What is an Aufbau diagram?
The idea that before 2 electrons occupy any orbital in a sublevel, other orbitals in the same sublevel must each contain 1.
What is Hund's Rule?
This scientist was the first to account for energy levels with his model.
Who is Niels Bohr?/Who is Bohr?
In the Schrodinger model, regions around the nucleus where there is zero chance of finding an electron.
What are nodes?
The orientation of an atomic orbital in space relative to the other orbitals in the atom.
What is the Magnetic Quantum Number (ml)?
An energy level diagram features this sublevel close to the top and furthest to the right.
What is the 4f sublevel?
The full electron configuration for Selenium.
What is 1s2, 2s2, 2p6, 3s2, 3p6, 4s2, 3d10, 4p4?
