In the late 1960s, a harder form of rock music called "heavy metal" was invented. The first use of the term was in a 1968 song by Steppenwolf, "Born to be Wild", and other early heavy metal bands appeared in the same year, such as Blue Cheer. Heavy metal music was mostly based on the sounds of the electric guitar.
Correspondingly, what makes a metal heavy?
The term heavy metal refers to any metallic chemical element that has a relatively high density and is toxic or poisonous at low concentrations. Examples of heavy metals include mercury (Hg), cadmium (Cd), arsenic (As), chromium (Cr), thallium (Tl), and lead (Pb).
Which is the heaviest metal in the world?
I assume by "heaviest," you mean "densest;" in that case, the densest chemical element is osmium (which is a metal). Osmium has a density of around 22 grams per cubic centimeter, about twice the density of lead! Answer 3: The heaviest naturally occurring element is plutonium measured by the mass of the element.
What is heavier metal?
Heavy metals are generally defined as metals with relatively high densities, atomic weights, or atomic numbers. The criteria used, and whether metalloids are included, vary depending on the author and context. Other heavy metals, such as cadmium, mercury, and lead, are highly poisonous.
