Answer 1

$\huge\blue{Answer}$

There is a way to estimate the speed of an electron in an atom. Its momentum is roughly (Planck’s constant) / (extent of orbital), and one divides by the electron’s mass to get its velocity. Or strictly speaking, (Lorentz factor) * (velocity), where (Lorentz factor) = (1 - (v/c)^2)^(-1/2) for velocity v.

A hydrogen atom has size 0.5 angstroms or 0.05 nanometers, giving its electron a speed of about 0.0073 c or 2200 km/s. For larger atoms, the outermost electrons usually travel slower than that, but their innermost ones typically travel much faster, for heavy elements close to c
