Question

_________ are examples of isobars.

• A. ${}_{14}S{i}^{31}{,}_{15}{P}^{32}$
• B. ${}_6{C}^{13}{,}_7{N}^{13}$
• C. ${}_7{N}^{14}{,}_7{N}^{15}$
• D. None of the above

Answer 1

The correct option is B ${}_6{C}^{13}{,}_7{N}^{13}$

Isobars are atoms or nuclides of separate chemical elements having the same number of nucleons (protons $+$ neutrons)

${\therefore }_6{C}^{13}{,}_7{N}^{13}$ are isobars as it contains same number of nucleons
