Question

An α-particle is bombarded on ¹⁴N. As a result, a ¹⁷O nucleus is formed and a particle is emitted. This particle is a

Options

• neutron

• proton

• electron

• positron

Answer 1

proton

If an alpha particle is bombarded on a nitrogen (N-14) nucleus, an oxygen (O-17) nucleus and a proton are released.
According to the conservation of mass and charge,

`"_2^4He + _7^14N →  _6^17O + _1^1P`

So, the emitted particle is a proton.
