Explanation:

Question 6

The \(p\) atomic orbitals have a dumbbell - shaped electron density distribution. The \(3p\) orbital is a type of \(p\) orbital. A sphere - shaped orbital is an \(s\) orbital (\(d\) is wrong). A bar - shaped orbital does not exist (\(b\) is wrong). Two perpendicular dumbbells are not the shape of a single \(p\) orbital (\(c\) is wrong).

For a given principal energy level, the number of \(d\) orbitals is determined by the magnetic quantum number (\(m_l\)). For \(d\) orbitals (\(l = 2\)), \(m_l=- 2,-1,0,1,2\). Each value of \(m_l\) corresponds to one orbital. So, there are \(5\) \(d\) orbitals in a principal energy level.

For \(p\) orbitals (\(l = 1\)), the values of the magnetic quantum number \(m_l=-1,0,1\). Each value of \(m_l\) represents one orbital. So, the maximum number of orbitals in the \(p\) sublevel is \(3\).

A. dumbbell
