quantum theory Flashcards
what is a quanta
the amount of energy needed to move from one energy level to another
energy is quantized, therefore it…
comes in chunks
what does the quantum mechanical model do?
explains the manner in which electrons exist and behave in atoms
what is the aufbau principle?
the idea that electrons enter the lowest energy level before reaching higher ones
how many orbitals are there and what are they called?
4; s,p,d,f
what is the principle quantum number and what is it’s variable?
the energy level of an electron; n
what are atomic orbitals?
regions where there is a high chance of finding an electron
what does the principle energy number indicate
how close the electron is to the nucleus (the bigger the number, the farther away)
how to find the total amount of electrons in an energy level (formula)
2n^2 (n=energy level)
in the aufbau diagram, how many boxes are there in orbital s
1
in the aufbau diagram how many boxes are in orbital p
3
in the aufbau diagram how many boxes are in orbital d
5
in the aufbau diagram how many boxes are in orbital f
7
how do you find the max amount of electrons allowed in each orbital?
times the amount of boxes by 2
pauli exclusion principle
2 electrons max; different spins
