Actinide is not an element, but is a series of elements. Of the actinide series of elements, all except actinium, thorium, protactinium, and uranium are considered to be synthetic elements because they are not found in nature in appreciable amounts.
Einsteinium is the element named after Albert Einstein. It is a synthetic element with the atomic number 99 and is part of the actinide series on the periodic table.
Einsteinium (Es) is only an artificial, unstable, radioactive metal member of the actinides family.
Americium is considered an inner transition metal.
Seaborgium is a synthetic element that belongs to the category of transition metals on the periodic table. It is a highly radioactive metal and is the heaviest element in the actinide series.
The symbol Md stands for the element Mendelevium, which is a synthetic element and part of the actinide series. It is named after Dmitri Mendeleev, the Russian chemist who is known for creating the periodic table.
Californium (Cf, 98th element) is a transuranic actinide, so it is a metal.Added:Cf is a synthetic radioactive metallic chemical element.
Einsteinium is the element named after Albert Einstein. It is a synthetic element with the atomic number 99 and is part of the actinide series on the periodic table.
Einsteinium (Es) is only an artificial, unstable, radioactive metal member of the actinides family.
Americium is considered an inner transition metal.
Nobelium, with the chemical symbol No, is the chemical element with the atomic number 102.
Seaborgium is a synthetic element that belongs to the category of transition metals on the periodic table. It is a highly radioactive metal and is the heaviest element in the actinide series.
The symbol Md stands for the element Mendelevium, which is a synthetic element and part of the actinide series. It is named after Dmitri Mendeleev, the Russian chemist who is known for creating the periodic table.
A synthetic element that is also a transition metal is named "rutherfordium." It is element 104 on the periodic table and belongs to the transition metal group. Rutherfordium is produced in nuclear reactors by bombarding actinide elements with high-energy particles.
Plutonium is an actinide
Actinide
The hardness of berkelium, a synthetic element, has not been specifically measured. However, as a general trend for actinide elements, berkelium is expected to be relatively soft, like most metals in the actinide series.
Americium is in the Actinide family of elements. It is a synthetic element with the symbol Am and atomic number 95. Actinides are a series of elements in the periodic table that have properties similar to actinium.
