Question

In 1932, James Chadwick bombarded beryllium-9 with alpha particles. One product was a neutron. This led to the direct experimental verification of the existence of neutrons. The other product of Chadwick's nuclear reaction was carbon-12. boron-12. helium-4. nitrogen-14.

Answer 1

Answer:  The other product of Chadwick's nuclear reaction was carbon-12.

Explanation:

The isotopic representation of an atom is: $_Z^A\textrm{X}$

where,

Z = Atomic number of the atom

A = Mass number of the atom

X = Symbol of the atom

In a nuclear reaction, the total mass and total atomic number remains the same.

For the given reaction:

$^{9}_{4}\textrm{Be}+^4_2\textrm{He}\rightarrow ^{A}_{Z}\textrm{Kr}+^1_0\textrm{n}$

To calculate A:

Total mass on reactant side = total mass on product side

9 + 4= A + 1

A = 12

To calculate Z:

Total atomic number on reactant side = total atomic number on product side

4 + 2 = Z + 0

Z = 6

The isotopic symbol is $_{6}^{12}\textrm{C}$ . Thus The other product of Chadwick's nuclear reaction was carbon-12.
