Explanation:

Question 8

In atomic structure, for the \(p\) sublevel, the magnetic quantum number \(m_l\) values are \(- 1,0,+1\). Each \(m_l\) value corresponds to one orbital.

The formula for the maximum number of electrons in a principal energy level \(n\) is \(2n^{2}\). For \(n = 2\), \(2\times2^{2}=8\).

When an electron moves from a lower to a higher energy level, according to the quantum theory of atomic structure, it absorbs a discrete amount of energy (a quantum of energy). It does not double its energy (not a fixed - doubling rule), does not absorb a continuously variable amount (energy levels are quantized), and moving to a higher energy level means moving farther from the nucleus.
