2.2 Flashcards
What is number of orbitals
N
M?
Bcs it determine bumber of orientation?
Definition of an orbital
A region in space about the nucleus in which the probability of finding an electron is high
Ig.
there are a lot of electron can be found
Give characteristics of on electron in an atom (the quantum numbers )
Principal quantum number (n) - size
And energy level
Angular momentum quantum number (π) - shape
l
What is in the same shell?
Alp orbitals that have the same-value of n
What does this mean?
It means that whatever orientation, shape and spin if they have the same n (the quantum number and the energy levels) they will live thw save shells aka the orbit/petala
Relation of n
ο the distance between the Δ from the nucleus of the atom.
(n ο, average distance between Δ and the nucleus ο) ο the energy of the orbital.
(n ο, energies of the orbitals ο
What does angular momentum (l) do/describe?
Divide the shell i to small froup of orbitals: subshells
What does value of l indicates (azimuthal quantim numbers)
The value of l indicates:
The shape of the atomic orbital,
the type of orbital,
the angular momentum of the electron.
Whatβs the type of orbital?
The shape and notation
S - sphere
P - dumbbell
D - cloverleaf
F
How to determine the orbital shape with value of l
L is 0,1,2,3
0- s
1-p
2-d
3-f
How to determine the subshell?
(Amount of l-the range)(notation of orbital shape)
Eg
N=2 L= 1,2 Subshell= 2s ββ> because l=1. Notation is s 2p
Relation of n and size of s(sphere shape)
N brtambah
Size shape brtmabh
How many orientation does the shape of `dβ (cloverleaf) have
5
What is l/ azimuthal quantum number/
Angular momentum
It indicates the shape of the atomic orbital
How to draw shape of d orbital
Dz^2
Ans dx^2 -y^2
Dumbell and donut
2.
Clover leaf on x and y
What is m, magnetic quantum number
N
