<h3>
What are heavy metals?</h3>
A heavy metals are generally defined as metals with relatively high densities, atomic weight and atomic number.
They toxic and poisonous in nature. They occurs naturally and are very essential to life.
Arsenic, cadmium, lead, copper, nickel and mercury are the most commonly used heavy metals.
Electron staining means to absorb heavy metals of high scattering power to biological specimens which exhibit a small scattering power for electrons.
Thus, the elements of heavy metals are used to absorb electrons in electron-dense stains.
