The atomic mass of lead is 208 and its atomic number is 82. The atomic mass of bismuth is 209 and its atomic number is 83. The ratio of neutrons/protons in the atom

A

Higher of lead

B

Higher of bismuth

C

Same

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
A
`n/p` of `""_(82)Pb^(208) = (126)/(82) = 1.53`
`n/p ` of `""_(83)Bi^(209)= (126)/(83) = 1.51`
