Question 10

Two of the isotopes of helium are helium-3 ( $23He^{3}_{2}\text{He}$ ) and helium-4 ( $24He^{4}_{2}\text{He}$ ).

State one similarity in the composition of their nuclei.

[1]

Describe how a nucleus of helium-4 differs from a nucleus of helium-3.

[1]

In a nuclear fusion reaction, a nucleus of helium-3 fuses with another nucleus of helium-3 at extremely high temperatures. This fusion reaction produces a nucleus of element $Y\text{Y}$ and two protons ( $11H^{1}_{1}\text{H}$ ).

Explain why an extremely high temperature is needed when forcing these two nuclei together.

[3]

Using nuclide notation, complete the equation for this reaction:

^{3}_{2}\text{He} + \,^{3}_{2}\text{He} \rightarrow \text{\quad\quad\quad} + 2\,^{1}_{1}\text{H}
