a) Write the significance of quantum numbers n, l & m.
b) State Pauli’s exclusion principle.
c) Write the electronic configuration of copper (Z = 29).
Answers
Answer:
principal quantum number
azimuthal quantum number
magnetic quantum number
spin quantum number
Explanation:
a)n= Principal quantum number
n= 1,2,3,4
l= azimuthal quantum number
l= 0,1,2,3
s,p,d,f
m= magnetic quantum number
m= 2l+1
b) paulis exclusion principle: no two quantum numbers can have same set of all quantum numbers
two electrons in a orbit must have opposite spin
c) electronic configuration of copper
1s² 2s²2p⁶3s²3p⁶3d¹⁰4s¹(z=29)
Answer:
1 according to topper Quantum numbers are important because they can be used to determine the electron configuration of an atom and the probable location of the atoms electrons
Explanation:
2 pauli's exclusion principle states that no two electrons in the same atom can have identical values for all four of the quantum numbers
3. the atomic number of Goa is 29 its electronic configuration is 3G 101
