How many isotopes does Nb have?
Naturally occurring niobium ( 41 Nb) is composed of one stable isotope ( 93 Nb) . The most stable radioisotope is 92 Nb with a half-life of 34.7 million years. The next longest-lived niobium isotopes are 94 Nb (half-life: 20,300 years) and 91 Nb with a half-life of 680 years.
What is the most stable element?
There are some 90+ elements of the periodic table that occur naturally in the Universe, but of them all, iron is the most stable. If you fuse lighter elements together to get closer to iron, you gain energy; the same is true if you split heavier elements apart.
How do you know if a nucleus is stable?
The principal factor for determining whether a nucleus is stable is the neutron to proton ratio . Elements with (Z<20) are lighter and these elements' nuclei and have a ratio of 1:1 and prefer to have the same amount of protons and neutrons.
What is the most stable isotope?
The element with the most stable isotopes is tin which has ten different stable isotopes. Many elements only exist in an unstable or radioactive form. All non-natural or man-made elements are radioactive isotopes.
Which is the rarest element on the Earth?
A team of researchers using the ISOLDE nuclear-physics facility at CERN has measured for the first time the so-called electron affinity of the chemical element astatine , the rarest naturally occurring element on Earth.
What is the symbol of uranium?
Uranium- is a silver-fray metallic chemical element. Uranium is in the periodic table that has a symbol U and atomic number 92. It also has the highest atomic weight of the naturally occurring elements.
What letter is never used in any element symbol?
The Letter Q
Note that the letter “Q” does not appear in any official element names. Temporary element names, such as ununquadium, contain this letter.
