Question

to show the electron configuration for an atom, when would it be better to use an orbital notation than to use a written configuration with numbers, letters, and superscripts?○ when the aim is to use less space○ when the aim is to show electron spins○ when the aim is to show orbital shapes in subshells○ when the aim is to show electron distributions in shells

Explanation:

electrons in subshells. Orbital notation (e.g., box diagrams) explicitly represents individual orbitals and can show the spin state of each electron using arrows, which written configurations cannot do. The other options are incorrect: written configurations use less space, neither notation shows orbital shapes, and both can show shell-level electron distributions.
