Electron Configuration Flashcards
Bohr model
Electrons travel in orbits -farther orbit from the nucleus the higher the energy.
Excited state
The state when the electron is filled with energy and is at a higher orbital.
Orbital
An area that is similar to an orbit, but there is a 90% chance of finding the electron inside the circle. Usually a circle.
Rutherford
discovered the positive nucleus, he used the gold foil experiment (his model was the peach pit)
Orbit
A sphere of activity, you are almost guaranteed to find the electron on this path
Thompson model
Thompson model, discovered the electron. Used the plum pudding model.(fuzzy clouds of electrons)
Shrodinger
father of quantum mechanics, regular physics doesn’t apply to quantum mechanics.
Ground state
The ground state is the state that the electron Is in before it is energized.
Aufbau
The principle that says that electrons fill up the lower energy levels first
Quantum mechanics
The study of how particles interact at a nanoscopic level.
Orbital filling diagram
It is the one with the boxes and the arrows.
Electron configuration diagram
The one without the boxes and arrows
To find the coefficient for the p and s orbitals…
You look at which period it is in… (The horizontal one)
To find the coefficient for a d orbital you…
Find the period and subtract 1
To find the coefficient for a f orbital you…
Look at the period and subtract 2
How many boxes and electrons can a s orbital hold.
1 boxes = 2 electrons
How many boxes and electrons can a p orbital hold.
3 boxes and six electrons
How many boxes and electrons can a d orbital hold.
5 boxes and ten electrons
How many boxes and electrons can a f orbital hold.
7 boxes and 14 electrons
Pneumonic name for a s electron
Sphere
Pneumonic name for a p electron
Peanut
Pneumonic name for a d electron
Daisy
Pneumonic name for a f electron
No picture -too messed up or too “f”ed up.
Pauli exclusion principle
In each box of an electron filling diagram the electrons spin differently
How to do gas notation steps
1.Find the element you are looking on the periodic table. 2. Find the noble gas that is located before it (the closest one) 3. Write it in brackets. Then continue with electron notation or the diagram from there.
