The elements of heavy metals are used to absorb electrons in electron-dense stains.
<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.

Answer: The atoms of the solid products are tightly packed whereas those in gas are loose.
Explanation:
Atoms in the solid structure are linked to each other by strong force of attraction and they collectively form an three-dimensional structure. The binding of the atoms form the shape of the solid product. The gas exhibit free atoms in it. The atoms are not linked to one another by strong force of attraction. The atoms as a part of gas have higher energy as those present in the solid products. So, the atoms of the gas wander freely as compared to those in the solid products.
Answer:
the formula of its oxide is X2O3.
