Question

In which of the following pairs do the two species resemble each other closely in chemical properties?

• A. ${}_1^{1}H$ and ${}_1^{2}H$
• B. ${}_8^{16}{O}^{}$ and ${}_8^{16}{O}^{2-}$
• C. ${}_{12}^{24}{Mg}^{}$ and ${}_{12}^{24}{Mg}^{2+}$
• D. ${}_7^{14}{N}^{}$ and ${}_7^{14}{N}^{3-}$

Answer 1

The correct option is A ${}_1^{1}H$ and ${}_1^{2}H$

Both ${}_1^{1}H$ and ${}_1^{2}H$ have 1 electron and are neutral as a whole which will result in similar chemical properties.
