Period 1 Science
A hug without U is like mercury. Hg. :))
-
Transition metal.
Liquid at room temperature.
Color is silver.
Mercury can be used to make thermometers, barometers and other
scientific instruments. Mercury conducts electricity and is used to
make silent, position dependent switches. Mercury vapor is used in
streetlights, fluorescent lamps and advertising signs.
- Named after the planet mercury, Mercury's chemical symbol comes
from the Greek word ​h
hydrargyrum​
ydrargyrum , which means "liquid silver."
- Mercury was known to the ancient Chinese, Egyptians and Hindus
and has been found in Egyptian tombs dating back to about 1500
B.C. Therefore, we do not know who discovered it.
- Mercury is not usually found free in nature and is primarily
obtained from the mineral cinnabar (HgS). ​SSpain​
pain and ​IItaly​
taly produce
about half of the world's supply of Mercury.
- Melting Point:
Point:​ 234.32 K (-38.83°C or -37.89°F)
- Boiling Point:
Point:​ 629.88 K (356.73°C or 674.11°F)
- Physical Properties: ​Mercury is the only liquid metal. Mercury can
be frozen (changed into a solid). It can be changed into a gas
("boiled"). It has a very high surface tension. Mercury is also a very
good conductor of electricity.
- Chemical Properties: ​Mercury is moderately active. It does not
react with ​o
oxygen
xygen ​in the air very readily. It reacts with some acids
when they are hot, but not with most cold acids.
