Is mercury a metal or a non metal?
mercury (Hg), also called quicksilver, chemical element, liquid metal of Group 12 (IIb, or zinc group) of the periodic table.
Why is mercury classified as a metal?
Mercury is the only metal that is liquid at standard conditions for temperature and pressure. Mercury is a poor conductor of heat, but a fair conductor of electricity. Mercury has a unique electron configuration which strongly resists removal of an electron, making it behave similarly to noble gas elements.
Is mercury a metal nonmetal or semimetal?
Metalloids
| Metals | Non-metals | Metalloids |
|---|---|---|
| Copper | Hydrogen | Arsenic |
| Iron | Nitrogen | Antimony |
| Mercury | Sulphur | Germanium |
| Zinc | Phosphorus |
Why mercury is not a metal?
Mercury is both a liquid at room temperature (as it has a very low melting point of -39C) and a metal. We tend to assume metals are all solids but they are not.
Is mercury a noble metal?
In chemistry, noble metals are metallic elements that show outstanding resistance to chemical attack even at high temperatures. More inclusive lists include one or more of copper (Cu), rhenium (Re), and mercury (Hg) as noble metals.
Is Mercury semi metal?
Distinction Between Semimetals and Metalloids An example of a semimetal compound is mercury telluride (HgTe). Other scientists consider arsenic, antimony, bismuth, the alpha allotrope of tin (α-tin), and the graphite allotrope of carbon to be semimetals.
Can you buy mercury in California?
California law restricts the level of mercury in some products (such as general purpose lights and packaging), and bans the sale of other mercury-containing products outright (such as mercury-containing thermometers, blood pressure cuffs, etc.).
