# When a Boron Nucleus ( 10 5 B ) is Bombarded by a Neutron, a α-particle is Emitted. Which Nucleus Will Be Formed as a Result? - Physics

ConceptNuclear Energy Controlled Thermonuclear Fusion

#### Question

When a boron nucleus (""_5^10"B") is bombarded by a neutron, a α-particle is emitted. Which nucleus will be formed as a result?

#### Solution

It is given that when a boron nucleus (""_5^10"B") is bombarded by a neutron, an α-particle is emitted.

Let X nucleus be formed as a result of the bombardment.
According to the charge and mass conservation,

""_5^10"B" + _0^1n → X + _2^4He

Charge : 5  0  3  2

Mass : 10 1 7 4

The mass number of X should be 7 and its atomic number should be 3.

therefore X =  _3^7Li

Is there an error in this question or solution?
