Einsteinium(III) chloride is a chloride of einsteinium.


Einsteinium(III) chloride is created by reacting einsteinium metal with dry hydrogen chloride gas for 20 minutes at 500 °C which crystallized around 425 °C. [1]

2Es + 6HCl → 2EsCl3 + 3H2

The actinide or actinoid series encompasses the 15 metallic chemical elements with atomic numbers from 89 to 103, actinium through lawrencium. The actinide series derives its name from the first element in the series, actinium. The informal chemical symbol An is used in general discussions of actinide chemistry to refer to any actinide.

Einsteinium Chemical element, symbol Es and atomic number 99

Einsteinium is a synthetic element with the symbol Es and atomic number 99. Einsteinium is a member of the actinide series and it is the seventh transuranic element. It was named in honor of Albert Einstein.

Fermium Chemical element, symbol Fm and atomic number 100

Fermium is a synthetic element with the symbol Fm and atomic number 100. It is an actinide and the heaviest element that can be formed by neutron bombardment of lighter elements, and hence the last element that can be prepared in macroscopic quantities, although pure fermium metal has not yet been prepared. A total of 19 isotopes are known, with 257Fm being the longest-lived with a half-life of 100.5 days.

Mendelevium Chemical element, symbol Md and atomic number 101

Mendelevium is a synthetic element with the symbol Md and atomic number 101. A metallic radioactive transuranium element in the actinide series, it is the first element by atomic number that currently cannot be produced in macroscopic quantities through neutron bombardment of lighter elements. It is the third-to-last actinide and the ninth transuranic element. It can only be produced in particle accelerators by bombarding lighter elements with charged particles. A total of seventeen mendelevium isotopes are known, the most stable being 258Md with a half-life of 51 days; nevertheless, the shorter-lived 256Md is most commonly used in chemistry because it can be produced on a larger scale.
