Quantum Mechanical Model Flashcards
Who’s model is this?
Erwin Schrödinger
What is the purpose of the quantum mechanical model?
Uses mathematics to predict the probability of finding an electron at a certain location in an atom
What a subshells?
Some shows are represented as letters (s, p, d, f)
How many electrons can each orbital hold?
Each orbital can hold 2e -electrons
What is the Aufbau principle?
Energy shells fill from lowest energy to high, sub shells fill from the lowest energy to high
What is Pauli’s exclusion principle?
Single overall can hold a maximum of two electrons; Over those that are in the same shall have the same energy
What is Hunds rule?
When filling Orbitals that have the same energy place one electron in each before completing pairs
