Concept explainers
(a)
Interpretation:
The electronic configuration for Ti should be written using the orbital box diagram and the noble gas notation.
Concept Introduction:
The electronic configuration of an atom represents the arrangement of electrons in the subshells and orbital shells. Generally. Electronic configuration is used to define the atom’s orbitals in its ground state.
(b)
Interpretation:
The electronic configuration for Ti2 + should be written using the orbital box diagram and the noble gas notation.
