nobelium (No), synthetic chemical element of the actinoid series of the periodic table, atomic number 102. The element was named after Swedish chemist Alfred Nobel.

What is nobelium made up of?

Nobelium is made by bombarding curium with carbon in a device called a cyclotron.

What is nobelium symbol on the periodic table?

Nobelium is a chemical element with symbol No and atomic number 102.

Is nobelium a solid liquid or gas?

Nobelium is a chemical element with symbol No and atomic number 102. Classified as an actinide, Nobelium is a solid at room temperature.

Is nobelium found in the earth's crust?

Nobelium doesn't occur naturally, it has not yet been found in the earth's crust and it's so unstable that any amount formed would decompose to other elements very quickly.

What does nobelium look like?

It is not known what this rare earth metal looks like, but it is predicted to be a silvery-white or pale grey solid at room temperature. Nobelium was originally synthesised by a team at the Nobel Institute of Physics in Stockhlom, Sweden in 1957.

Why is nobelium the only actinides with two oxidation states?

After losing 2 electrons No forms No²⁺ ion, which is stable due to completely filled 5f-orbitals. ... Such extra stability due to completely filled orbital is not acquired by any other actinoid in their +2 oxidation state. Hence, nobelium is the only actinoid with a +2 oxidation state.

How do you make nobelium?

Nobelium is created by nuclear bombardment, and has only been produced in miniscule amounts. Nobelium can be produced by irradiating a californium-249 target with carbon-12 ions. Isotopes: Nobelium has 12 isotopes whose half-lives are known, with mass numbers 250 to 262.

How is nobelium made in the universe?

Nobelium is produced via nuclear bombardment of californium-249 or other transuranium atoms with carbon-12 ions in the cyclotron.

What is the definition of nobelium?

: a radioactive metallic element produced artificially — see Chemical Elements Table.

What is the element name of LR?

Lawrencium is a chemical element with symbol Lr and atomic number 103.

How many isotopes does nobelium have?

Thirteen isotopes of nobelium are known, with mass numbers 249–260 and 262; all are radioactive.

Is Cu+ paramagnetic or diamagnetic?

In Cu⁺ the electronic configuration is 3d¹⁰ completely filled d- shell thus it is diamagnetic. thus it has one unpaired electron in d- subshell thus it is paramagnetic.
