(a)
Interpretation:
Ground-state electronic configuration of yttrium has to be written in noble-gas shorthand notation using the periodic table.
Concept Introduction:
Electrons of an atom are arranged in orbitals by the order of increasing energy. This arrangement is known as electronic configuration of atom. This can be represented using noble-gas shorthand notation also.
In the noble-gas shorthand notation of electronic configuration, the electrons that are in excess in comparison with the nearest noble gas is written. The symbol of nearest noble-gas is written in square brackets followed by the excess electrons.
(b)
Interpretation:
Ground-state electronic configuration of polonium has to be written in noble-gas shorthand notation using the periodic table.
