What is 94 on the periodic table?
plutonium
This first produced neptunium-238 with a half-life of two days, and this decayed by beta emission to form element 94 (plutonium).
What has an atomic number of 94?
Plutonium
Plutonium; Plutonium or Pu is a radioactive and metallic element with an atomic number of 94. Plutonium is silvery in pure form, but has a yellow tarnish when oxidized. Plutonium, with the chemical formula Pu, is element 94 of the periodic table.

What does berkelium look like?
Berkelium is a soft, silvery-white, radioactive metal. The berkelium-249 isotope emits low-energy electrons and thus is relatively safe to handle. It decays with a half-life of 330 days to californium-249, which is a strong emitter of ionizing alpha particles.
Can you handle plutonium?
Is it a metal like uranium? A: Plutonium is, in fact, a metal very like uranium. If you hold it [in] your hand (and I’ve held tons of it my hand, a pound or two at a time), it’s heavy, like lead. It’s toxic, like lead or arsenic, but not much more so.
Who was plutonium discovered by?

On March 21, 1942, the chemical element with the atomic number 94 was given the name plutonium, after the dwarf planet Pluto. Discovered by Glenn Seaborg, Edwin McMillan, and their colleagues, plutonium is a radioactive element that can be used to both create and destroy.
Is plutonium reactive?
It is chemically reactive. A relatively large piece of plutonium is warm to the touch because of the energy given off in alpha decay. Larger pieces will produce enough heat to boil water. The metal readily dissolves in concentrated hydrochloric acid, hydroiodic acid, or perchloric acid.
Is Bk a metal?
Berkelium is a radioactive metallic element that is a member of the actinide group of elements. It is silvery in colour and its chemistry has been investigated to a limited extent and several compounds have been made. Berkelim metal is attacked by oxygen, steam and acids, but not by alkalis.
What can you use berkelium for?
Berkelium-249 (330-day half-life) has been widely used in the chemical studies of the element because it can be produced in weighable amounts that are isotopically pure by nuclear reactions beginning with curium-244. The only use of berkelium has been in the synthesis of heavier elements such as tennessine.
How to find the crystal structure of periodic table?

What is the periodic table?
The periodic table is a graphic description of the periodic law, which states that the properties and atomic structures of the chemical elements are a periodic function of their atomic number.
