(a)
Interpretation:
Based on principles of writing electronic configuration, write the correct condensed electronic ground state configuration for
Rb
Concept introduction:
The electronic configuration is based on the following rules
- Pauli’s exclusion principle (no two electrons in the same element can have all the four quantum numbers same)
- Hund’s rule of multiplicity ( the electrons are first filled in all the degenerate orbitals and then pairing starts)
- Pauli’s exclusion principle (the electrons are filled based on the energy of orbitals)
(b)
Interpretation:
Based on principles of writing electronic configuration, write the correct condensed electronic ground state configuration for
Sr
Concept introduction:
The electronic configuration is based on the following rules
- Pauli’s exclusion principle (no two electrons in the same element can have all the four quantum numbers same)
- Hund’s rule of multiplicity ( the electrons are first filled in all the degenerate orbitals and then pairing starts)
- Pauli’s exclusion principle (the electrons are filled based on the energy of orbitals)
(c)
Interpretation:
Based on principles of writing electronic configuration, write the correct condensed electronic ground state configuration for
Br
Concept introduction:
The electronic configuration is based on following rules
