Atoms have a radius of about 1x10^-10 m

Electrons are arranged at different distances to the nucleus

The radius of a nucleus is less than 1/10000 of the radius of an atom

Most of the mass is at the nucleus

Protons have a relative charge of +1 (in SI this is 1.6x10^-19C)

Protons have a relative atomic mass of 1 (in SI this is 1.67x10^-27)

Electrons have a relative charge of -1 (in SI this is -1.6x10^-19C)

Electrons have a relative atomic mass of 1/2000 (in SI this is 9.11x10^-31)

Neutrons have a relative charge of 0- they are neutral

Atomic mass of +1.

Specific charge C/kg) = Charge (C) / Mass (kg)
