Edexcel A-Level Physics Nuclear and particle physics overview quiz quiz

The atom is solid throughout

The atom is mostly empty space

Alpha particles are negatively charged

The nucleus is large

The number of neutrons

The number of nucleons

The number of protons

The number of electrons

$R = r_0 A$

$R = r_0 A^2$

$R = \frac{r_0}{A}$

$R = r_0 A^{1/3}$

Three quarks

A quark and an antiquark

Two leptons

A proton and a neutron

Alpha

Gamma

Beta

They are equal

Predictable for each individual nucleus

Dependent on temperature

Random and spontaneous

Triggered by external radiation

$A = \frac{N}{\lambda}$

$A = \frac{\lambda}{N}$

$A = \lambda + N$

$A = \lambda N$

$\frac{1}{8}$

$\frac{1}{2}$

$\frac{1}{4}$

$\frac{1}{16}$

At the lightest nuclei such as hydrogen

Near iron-56 at the peak

At the heaviest nuclei such as uranium

There is no peak

$E = mc$

$E = \frac{1}{2}mc^2$

$E = mc^2$

$E = \frac{m}{c^2}$
