Nitrogen in Cosmic Rays

Chemistry Level 1

$_7^{14}N + n \space \rightarrow \space _?^?X + ^3_1T$ Cosmic rays can irradiate neutrons ( $n$ ). In the above reaction, a $n$ joins a nitrogen atom in the atmosphere, producing a Tritium ( $T$ ) atom and one other atom ( $X$ ). Determine the identity of X and give your answer as the mass number divided by the atomic number.

$_7^{14}N + _0^1n \space \rightarrow \space _?^?X + ^3_1T \\ _?^?X = _7^{14} + _0^1 - _1^3 = _{7+0-1}^{14+1-3} = _6^{12}X \\ X = \text{Carbon} = C \\ \text{Mass \# = } 12 \\ \text{Atomic \# = } 6 \\ Answer = \frac{12}{6} = \boxed{2.0}$
