    An isotone of \[{}_{14}S{{i}^{30}}\] is:

    A)  \[{}_{15}{{P}^{30}}\]     

    B)         \[{}_{14}S{{i}^{29}}\]    

    C)         \[{}_{14}{{P}^{31}}\]     

    D)         \[{{P}^{\,+}}\]

    Correct Answer: C

    Solution :

    Isotones are the species having equal number of neutrons. Hence, isotone of \[{}_{14}S{{i}^{30}}(n=16)\] is\[{}_{15}{{P}^{31}}(n=31-15=16)\].
