Nucleus contains more than 99.9% of mass of atom

Nucleus does not have sharp boundary

Density of all elements is nearly the same

X-rays spectrum of all wavelengths starting from a minimum wavelength,is called continuous spectrum

X-ray lines corresponding to certain wavelength are called characteristic spectrum

Continuous X-ray spectrum depends on the type of target material

Characteristic X-ray spectrum depends on potential applied
