Question 1

pauli exclusion principle

Answer 1

electron is an atom described with four quantum numbers (n,l,m)
how electrons occupy the orbital
no two electrons in the same atom have the same quantum number

Question 1

consequences of principle

Answer 1

electron can share the same orbital provided ms is different
2 electrons per orbital with opposite spins

Question 3

electronic configuration

Answer 3

arrangement of electrons in an atom
energy of the atomic orbital increases, as n increases
size of the atomic orbital increases with n
electrons spend more time further away from nucleus, higher energy
electron repulsion makes the energy of subshell differ with increasing l
