History of Seaborgium
Properties:
Real Life Applications:
- Stainless Steel
- Cars
- Bicycles
- Taps
- Melting point 3465 °F (1907 °C)
- Does not react to water
- Unstable in oxygen (immediately forms a thin oxide layer to protect the metal)
A team of scientists led by Albert Ghiorso discovered Seaborgium in 1974. The Joint Institute for Nuclear Research at Dubna, Russia and Lawrence-Berkeley
Laboratory, USA worked
together on the discovery. The
element was named after
Glenn Theodore Seaborg, a
Noble Prize Winner also a
American nulcear chemist.

Properties:
Real Life Applications:
Group 6b has 4 elements, Chromium, Molybdenum, Tungsten, and Seaborigum. All 4 of them have 2 electrons in their outer shell.
- Light Bulbs
- Window Heating
- Ballpoint pen
- Vibration alert on phones
- Automatic watches
- Melting point 6191°F (3422 °C)
- Does not react with water and oxygen
- It has excellent corrosion resistance and is attacked only slightly by most mineral acids.
History of Tungsten
Peter Woufle inspected a mineral that has a different type of metal. However his research didn't lead to a discovery. In fact a Spanish chemist and mineralogist Juan Jose de Elhuyar worked together with
his brother Fausto to discover
Tungsten. The brothers acidified
charcoal with wolframite that took
form of Tungsten.
History of Chromium:
Properties
Real Life Application:
A French chemist Nicolas Louis Vauquelin discovered the element Chromium in 1780. He boiled the crushed mineral with potassium carbonate to
produce lead carbonate,
which lead to the discovery of
a new element, Chromium.
- Alloy with steel
- Cutting tools
- Electrical filaments
- Melting point 4,753°F (2623°C)
- Does not react to water and oxygen
- Alloy with steel and/or nickle-base it enhances toughness, strength, weldability, and hardenability.
Properties:
Real Life Applications:
- Not applied in real life
- A lot of things about this element is unknown
History of Molybdenum
A Swedish scientist Carl Wilhelm
Scheele discovered Molybdenum in
1778. His friend Peter Jacob Hjelm
seperated the metal and ground them
both together using linseed oil. That
formed a paste which was heated up
in a closed crucible which created
a new metallic element.
