What is the mass of sodium if its relative atomic mass is 22.99?

Quark Calculations  Complete the following table.

Why was gold one of the first materials to be tested with this process?

• It is ductile so it is easily formed into a thin sheet

• It is heavy, so the nucleus would be heavy, ensuring that the nucleus was not ‘knocked out’ by the alpha particles.

What changes occur in element X after it undergoes beta plus decay?

• Proton in the nucleus becomes a neutron

• Electron created + emitted

• RELATIVE ATOMIC MASS

• PROTON NUMBER
