What particle is needed to complete the following equation?<br> 14/7N + ____ ---> 14/6C + 1/1H

yawa3891 [41]

Explanation:

The given reaction equation is as follows.

$^{14}_{7}N$ + ___ $\rightarrow ^{14}_{6}C + ^{1}_{1}H$

As there is release of one hydrogen which shows that mass number has increase by 1 on the product side.

Therefore, particle $^{1}_{0}n$ must be added in order to balance the given reaction equation.

Hence, the complete reaction equation will be as follows.

$^{14}_{7}N + ^{1}_{0}n \rightarrow ^{14}_{6}C + ^{1}_{1}H$
