Amongst the three isotopes of Neon - $_{10}^{20} N e,_{10}^{21} N e$ and $_{10}^{22} N e$ the nucleus with the lowest $n / p$ ratio is

Options:

Answer:

Solution:

$_{10}^{20} N e$ , $Z = 10$ , $A = 20$ , $N = A - Z$ , $= 10$ , $n / p = 1$

$_{10}^{21} N e, Z = 10, A = 21, N = A - Z = 11, \frac{n}{p} = \frac{11}{10} = 1.1$

$_{10}^{22} N e, Z = 10, A = 22, N = A - Z = 12, \frac{n}{p} = \frac{12}{10} = 1.2$
