# An α-particle is Bombarded on 14n. as a Result, a 17o Nucleus is Formed and a Particle is Emitted. this Particle is a - Physics

MCQ

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

• neutron

• proton

• electron

• positron

#### Solution

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.
