    The total number of orbital up to \[n=4\] are

    A)  \[2\]                                    

    B) \[16\]

    C)  \[32\]                                  

    D)  \[30\]

    Correct Answer: D

    Solution :

                    \[n=1\], no. of orbital \[=1(s)\] \[n=2\], no. of orbitals \[=4\] (5 and p) \[n=3\], no. of orbitals \[=9\](s p, d) \[\frac{\text{n = 4 }no.\text{ }of\text{ }orbitals\,\,(e\text{ }p,\text{ }d,\text{ }f)}{Total\text{ }no.\text{ }of\text{ }orbitals=30}\]
