Orbitals Flashcards
What does n indicate?
n is the principal quantum number and it represents an energy level
What does Bohr’s model indicate?
It states that electrons can only move between orbits, never moving halfway
Why do electrons repel each other?
Due to their negative charge
What happens to the size of orbits as n increases?
Orbits (shells) get larger as n increases
What happens to the energy of the electrons as n increases?
The energy of the electrons increases
List the first four sublevels.
s, p, d, f
How many sublevels are in n=1 and what are they called
There is only the s sublevel
How many sublevels are in n=2 and what are they called?
There is the s and p levels
How many sublevels are in n=3 and what are they called?
There is the s, p and d levels
How many sublevels are in n=4 and what are they called?
There is the s, p, d and f sublevel
How many electrons can s hold?
Up to 2 electrons
How many electrons can p hold?
Up to 6 electrons
How many electrons can d hold?
Up to 10 electrons
How many electrons can f hold?
Up to 14 electrons
Describe the energy difference in each sublevel.
2
S is the smallest subshell and has the lowest energy
F is the largest subshell and has the highest energy
What is an orbital?
The region in space where there is a high probability of finding an electron with a given energy
What does n mean?
The principle quantum number
What does the principle quantum number describe?
The size of the orbital the electron is in
What does I mean?
The orbital quantum number
What does the orbital quantum number describe?
The shape of the orbital
What does m(I) mean?
The magnetic quantum number
What does the magnetic quantum number mean?
The orientation of the orbital in space
What does m(s) mean?
The electron spin number
What does the electron spin number indicate?
The direction that the electron spins on its own axis
