When atoms of beryllium-9 are bombarded with alpha particles, neutrons are produced, the new isotope will be C-6.
In research, the physicist James Chadwick attacked Beryllium using alpha particles produced by the nuclear reactions of polonium naturally. High radiation penetration through some kind of lead shield was seen, which the then-current particle theories were unable to account for.
There was indeed the production of a carbon-12 nucleus as well as the production of a neutron whenever one blasted beryllium with alpha particles.
The reaction of alpha decay can be written as:
[tex]Be^{9} _{4} + He^{4} _{2}[/tex] → [tex]C^{12} _{6} + n^{1} _{0}[/tex]
Therefore, when atoms of beryllium-9 are bombarded with alpha particles, neutrons are produced, the new isotope will be C-6.
