Answer

3 Explanation 1. Determine the number of orbitals in the second shell The second electron shell corresponds to n=2. For n=2, there are two subshells: s and p. The p subshell has three orbitals (p_x, p_y, p_z). 2. Count distinct and degenerate p orbitals Each p orbital is distinct, and they are degenerate (same energy level). Therefore, there are 3 distinct and degenerate p orbitals.

Explanation

1. Determine the number of orbitals in the second shell<br /> The second electron shell corresponds to $n=2$. For $n=2$, there are two subshells: $s$ and $p$. The $p$ subshell has three orbitals ($p_x$, $p_y$, $p_z$).<br /><br />2. Count distinct and degenerate p orbitals<br /> Each $p$ orbital is distinct, and they are degenerate (same energy level). Therefore, there are 3 distinct and degenerate $p$ orbitals.
