Mercury is a very poisonous. Do not get it on your body because mercury can get into your skin even if you don't have a cut or injury. Remember, mercury is poisonous so don't get near it.
This element was named after the planet Mercury. Along time ago the Egyptians called it hydro-argyros which meant liquid silver or water silver. The Romans modified the name to Hydrargyrun. Hydrargyrun means liquid silver. Mercury can also be called quicksilver.
What mercury is in?
Mercury is in many things. It could be in thermometers (that’s how thermometers get its red color). Mercury is even in household switches. It's also in florescent lamps, and batteries. It use to be in toys, microwaves, and latex paint but they don't do that anymore.
Mercury is part of Zinc group and is mainly found in Cinnabar and Spain. It rarely occurs free in nature (that means that it rarely occurs alone in nature, not combined with something else).
The discovery of Mercury
The discoverer of mercury is unknown. We do know that it was found in Egyptian tombs long ago in the 1500 BC.

-Like mercury, lead is also poisonous.
The name lead comes from the Latin word plumbum. Plumbum, like hydrargyrun, means liquid silver.
What lead is in
Lead is mostly found in Lead sulfide. It is also in batteries, paint, soil, dust, and in drinking water. Yep, Lead is in drinking water. Lead is also in Link tanks.
Lead for water pipes
Lead has been known for a long time. The ancient Romans used lead to make water pipes. Some of the water pipes are made out of lead today.
Period number: 6
Group number: 14
What is Lead use for?
Lead may be poisonous but it can be used for many things. Again, lead can be used for water pipes. It can also be used for X-ray shields and Gamma-Ray radiation. Some of the alloys in lead are also used for things.
The discovery of Lead
The person who discovered lead is unknown. We do know that it was discovered about 7000 years ago.

Argon is part of the Noble gas group (argon is a type of gas) and the Carbon group.
The name Argon is from the Greek word Argos. Argos means inactive.
The discovery of Argon
Argon was discovered by Sir William Ramsay and Lord Raleigh. Sir William also discovered Krypton. It was found in Scotland in 1894.
Argon in Lamps
Argon is mixed with Krypos in fluorescent and incandescent lamps. The reason why is because it prevents oxygen from the hot filament.
Argon in the Earth
The Earth's atmosphere is 0.93% made out of argon. The Earth crust contains 1.2 of argon in it. In the water, there is 0.6 of Argon.
Mercury is not in the Earth's atmosphere. It is in the Earth's crust and water. There is 0.08 of mercury in the Earth's crust and there is 0.00003 of mercury in the Earth's ocean.
