Einsteinium is a synthetic chemical element; it has symbol Es and atomic number 99. It is named after Albert Einstein and is a member of the actinide series and the seventh transuranium element. Einsteinium was discovered as a component of the debris of the first hydrogen bomb explosion in 1952.

Einsteinium is named after the renowned physicist Albert Einstein. A vertical column in the periodic table. Members of a group typically have similar properties and electron configurations in their outer shell. A horizontal row in the periodic table. The atomic number of each element increases by one, reading from left to right.

Einsteinium is a chemical element with symbol Es and atomic number 99. Classified as a n actinide, Einsteinium is a solid at room temperature.

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.
