Structure and Properties Test Flashcards
The Principal Quantum Number
(n) all orbitals that have the same value of n are said to be in the same shell
The values of n can range from…
n = 1 to n = infinity
What happens as the value of n increases?
the energies of the orbitals also increases
The Secondary Quantum Number
(l) divides the shell into smaller groups of orbitals called subshells, determines the shape of the orbital
The number of subshells in a given shell = ?
n
When n = 1, l = ?
s
When n = 2, l = ?
s or p
When n = 3, l = ?
s, p, or d
When n = 4, l = ?
s, p, d, or f
Letter designation s = ?
l = 0
Letter designation p = ?
l = 1
Letter designation d = ?
l = 2
Letter designation f = ?
l = 3
The values of l can range from…
l = n-1
The values of ml can range from…
-l to +l
Max # of electrons per orbital =
2
of orbitals per shell =
n(squared)
of electrons per shell =
2n(squared)
Electron spin occurs because?
electrons behave as tiny magnets in which the revolving electrical charge of the electron creates its own magnetic field
The Spin Quantum Number
(ms) the spin can take on either of 2 possible values:
ms = +1/2
ms = –1/2
there can only be 2 electrons in one orbital with each spinning in the opposite direction
of orbitals =
n + value of letter
Value of letter: s =?
0
Value of letter: p =?
1
Value of letter: d =?
