What is plutonium on the periodic table?
plutonium (Pu), radioactive chemical element of the actinoid series of the periodic table, atomic number 94. It is the most important transuranium element because of its use as fuel in certain types of nuclear reactors and as an ingredient in nuclear weapons.

How many valence electrons does plutonium?
two electrons
Hence, plutonium has two electrons in its valence shell.
Is plutonium 239 stable?
Plutonium is not a stable element. As plutonium decays, it releases radiation and forms decay products. For example, the decay products of plutonium-238 and plutonium-239 are uranium- 234 and uranium-235. The decay process continues until a stable, non-radioactive decay product is formed.
What is plutonium Group and period?
The atomic symbol for plutonium is Pu, and it has an atomic number of 94 and atomic weight of 244. On a periodic table you will find plutonium in period 7 belonging to the group called actinides. Elements (such as plutonium) in the actinide family are all radioactive. Plutonium has a minimum of 15 different isotopes.
What is the atomic number of plutonium-239?

Why atomic radii increase down the group?
In general, the atomic radius decreases and increases in a group over a time. The number of energy levels (n) increases in a group downwards, since there is a larger distance between the nucleus and the outermost orbital. This results in an atomic radius that is greater.
What is atomic radii and ionic radii?
The atomic radius is half the diameter of a neutral atom. In other words, it is half the diameter of an atom, measuring across the outer stable electrons. The ionic radius is half the distance between two gas atoms that are just touching each other.
What is the radii of an atom?
Under most definitions the radii of isolated neutral atoms range between 30 and 300 pm (trillionths of a meter), or between 0.3 and 3 ångströms. Therefore, the radius of an atom is more than 10,000 times the radius of its nucleus (1–10 fm), and less than 1/1000 of the wavelength of visible light (400–700 nm).
