Question

multiple choice question
principal energy levels are divided into energy
suborbitals
shells
sublevels

Explanation:

In atomic structure, principal energy levels (denoted by \(n = 1,2,3,\cdots\)) are divided into energy sublevels. For example, when \(n = 2\), there are \(s\) and \(p\) sublevels. Sub - orbitals are part of sublevels (e.g., \(p\) sublevel has \(p_x\), \(p_y\), \(p_z\) sub - orbitals). Shells is another term for principal energy levels. So the correct answer is sublevels.

Answer:

C. sublevels
