The Density Of Metals

The density of metals ranges from Osmium at the highest density to lithium at the lowest density of any metal.

Knowing the periodic table is key for most scientists. But just merely knowing the name of each and every one of the elements is not enough.

There is a lot more information that scientists need to be au fait with. And density is one of them. So, what is the density of all metals?

What Is Density?

Before we go into the specific density for each of the metals in the periodic table, we need to understand what density actually is when we are talking about chemistry.

According to the Merriam Webster dictionary online, density is defined as follows:

The mass of a substance per unit volume”, or “the distribution of a quantity (such as mass, electricity, or energy) per unit usually of space (such as length, area, or volume).

To put it in simpler terms, the density of an element (metal or not) is the measure of mass per unit of volume.” It is important to note that all elements have density but in this article, we will just focus on the densities of metals, specifically.

What Are Metals?

Metals are elements that are easily recognized by their physical properties of solidity and because they have what we logically think of as a “metallic” luster.

“Life should be like precious metals: weigh much in little bulk.” — Seneca

Although metals tend to be strong, tough, and ductile, it is also true that they are malleable. Their melting points are high. Another characteristic of metals is that they can conduct electricity and heat. This is known as electrical and thermal conductivity.

Metals are often divided into base metals and precious metals. The defining difference between both categories of metals is that base metals oxidize easily while precious metals do not quite so easily.
