Even swallowing metallic mercury from a broken thermometer, a dental amalgam preparation, or pieces of an amalgam filling would not cause mercury poisoning. In contrast, breathing in large amounts of metallic mercury vapor can cause poisoning.

The periodic table of elements only includes individual chemical elements. Water is not found on the periodic table because it does not consist of a single element. ... The smallest particle of water is a water molecule, which is made of two atoms of hydrogen bonded to one atom of oxygen.

Mercury is a rocky planet with a huge iron core which makes up a large part of its interior. The core takes up nearly 3/4 of the planet's diameter. Mercury's iron core is about the size of the moon. Iron makes up about 70% of Mercury's total weight making Mercury the most iron-rich planet in the Solar System.

While both are terrestrial in nature, Mercury is significantly smaller and less massive than Earth, though it has a similar density. Mercury's composition is also much more metallic than that of Earth, and its 3:2 orbital resonance results in a single day being twice as long as a year.

There are no elements with the symbol “L” in the periodic table. ... Prehistorically it was named Plumbum and hence came its symbol Pb,much like Mercury which came from Hydrogyrum and is symbolised as Hg.
