What is dubnium color?
|Element Category:||transition metal|
|Group Period Block:||5 7 d|

Is dubnium harmful to humans?
Since Dubnium is not produced in high amounts and it does not exist even on the earth’s crust. Hence there are no such practical applications of this metal apart from the research areas. The metal has not also proved any harmful effects on health and the environment since it tends to decompose within a short period.
Where is dubnium naturally found?
|Atomic number (Z)||105|
What does dubnium react with?
Reaction of dubnium with the halogens
As only a little dubnium ever been made its reactivity with the halogens is unknown. One would predict its behaviour to be similar to that of tantalum (immediately above dubnium in the periodic table) and niobium (two places above).
How does dubnium look like?
|Classification:||Dubnium is a transition metal|
|Atomic weight:||268 no stable isotopes|
What type of element is dubnium?
radioactive transuranium element
dubnium (Db) an artificially produced radioactive transuranium element in Group Vb of the periodic table atomic number 105. The discovery of dubnium (element 105) like that of rutherfordium (element 104) has been a matter of dispute between Soviet and American scientists.
Is Dubnium a solid liquid or gas?
Dubnium is a chemical element with symbol Db and atomic number 105. Classified as a transition metal Dubnium is a solid at room temperature.
What is the atomic mass for Dubnium?
What makes dubnium unique?
Dubnium is a super-heavy or transactinide element. If a sufficient amount were ever produced its chemical properties are expected to be similar to that of the transition metals. It would be most similar to the element tantalum. Dubnium was first made by bombarding americium-243 with neon-22 atoms.
How was dubnium discovered produced in the universe?
Dubnium was first discovered in 1967 by scientists at the Joint Institute for Nuclear Research in Dubna while bombarding americium atoms with neon ions. In the same year a team from the University of California bombarded californium atoms with nitrogen ions and obtained dubnium-260.
When was dubnium discovered?
What’s the electronegativity of dubnium?
The first scale of electronegativity was developed by Linus Pauling and on his scale dubnium has a value of (no data) on a scale running from from about 0.7 (an estimate for francium) to 2.20 (for hydrogen) to 3.98 (fluorine).
What is dubnium room temperature?

How toxic is nobelium?
What is the freezing point of nobelium?
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.

What does nobelium do to your body?
Nobelium has no known biological role. It is toxic due to its radioactivity.
Is nobelium a noble gas?
|Naming||after Alfred Nobel|
|Discovery||Joint Institute for Nuclear Research (1966)|

Is nobelium a man made element?
Nobelium is named after Alfred Nobel the inventor of dynamite. It is a man-made element made in low quantities. It is a part of the actinide series.
Why is nobelium the only Actinoid 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.
Is nobelium paramagnetic or diamagnetic?
