A nuclide is represented by \(_{32}^{70}B\). Determine its neutron-proton ratio

A

0.5

B

0.8

C

1.2

D

1.5

correct option: c

The element B has a mass number 70 and atomic number 32.

Hence, B has 32 protons and (70-32) = 38 neutrons.

The neutron to proton ratio is 38:32 = \(\frac{38}{32} = 1.1875\)

\(\approxeq 1.2\)
