Einsteinium is a synthetic, silvery-white, radioactive metal. In the periodic table, it is located to the right of the actinide californium, to the left of the actinide fermium and below the lanthanide holmium with which it shares many similarities in physical and chemical properties.

What type of element is einsteinium?

einsteinium (Es), synthetic chemical element of the actinoid series of the periodic table, atomic number 99. Not occurring in nature, einsteinium (as the isotope einsteinium-253) was first produced by intense neutron irradiation of uranium-238 during the detonation of nuclear weapons.

Is einsteinium a transition metal?

Chemically, einsteinium behaves much like other actinides, which are essentially radioactive transition metals. It's a reactive element that exhibits multiple oxidation states and forms colored compounds. ... The most stable isotope is Es-252, which has a half-life of 471.7 days. Most isotopes decay within 30 minutes.
