The Heavy, Man-Made Element

Basic Information

• Element Name: Nobelium
• Symbol: No
• Discovered By: Scientists in Sweden and Russia
• Category: Actinide
• Group: Actinides series (no specific group like main groups)
• State: Synthetic (man-made), not found naturally
• Discovered In: 1957

Chemical Properties

• Atomic Number: 102
• Atomic Mass: Around 259 (most stable isotope)
• Valence Electrons: Usually 2 or 3 (typical of actinides)
• Electronic Configuration: [Rn] 5f¹⁴ 7s² (commonly accepted)

What You Should Know About Nobelium

• Nobelium is a synthetic element, created by nuclear reactions in labs.
• It belongs to the actinide series, a group of heavy, radioactive metals.
• Like other synthetic elements, Nobelium is highly radioactive and exists only briefly before decaying.
• Named after Alfred Nobel, the founder of the Nobel Prize.

Interesting Facts about Nobelium

• Nobelium is one of the heaviest elements created in the lab.
• It doesn’t have any stable isotopes — all of them decay quickly.
• Scientists study it to learn more about the chemistry of very heavy atoms.
• Because of its short life, it has no practical uses outside research.

Uses

• Used solely for scientific research to explore nuclear physics and chemistry.
• Helps expand knowledge about the properties of actinides and heavy elements.

✨ Summary:
Nobelium is a man-made, radioactive metal named in honor of Alfred Nobel. Though it exists only for a short time in labs, it helps scientists understand the behavior of the heaviest elements in the periodic table!
