Q
What is an atomic orbital?
A
A regional around the nucleus that c an hold up to 2 electrons with opposite spins.
2
Q
What is the order of filing of orbitals up to 4p?
A
1s,2s,2p,3s,3p,4s,3d,4p
3
Q
State the maximum number of electrons in each type of orbital
A
S=2 p=6 d=10 f=14
4
Q
How many orbitals filled according to to hundred’s rule?
A
Electrons occupy orbitals singly with parallel spins before paring, to minimise repulsion.
5
Q
What shape do s and p orbitals have?
A
S orbital = spherical
P orbital = dumbbell shaped.
6
Q
What does the Pauli exclusion principle state/
A
No 2 electrons in the same orbital can have the same set of 4 quantum numbers.
