# A N-14 nucleus is hit by a particle, forming a C-14 nucleus and a proton as the only products. How would you identify the type of particle which struck the N-14 nucleus?

(""_0^1 n)
""_7^14 N^o + ""_0^1 n => ""_6^14 C^o + ""_1^1p^
$\text{Mass" "Reactants" => 14 + 1 = "Mass""Products} \implies 14 + 1$
$\text{Charge" "Reactants" => 7 + 0 = "Charge" "Products} \implies 6 + 1$
