Curium (Cm), a synthetic chemical element of the actinide series Actinide elements, also known as actinide elements, Any of a series of 15 consecutive chemical elements in the periodic table from actinium to rhenium (atomic numbers 89-103). As a group, they are important mainly because of their radioactivity. https://www.britannica.com › Science › actinoid-element

Who discovered curium?

history.Curium was first The team of Glenn Seaborg, Ralph James and Albert Ghiorso In 1944, a cyclotron was used in Berkeley, California. They bombarded a block of the newly discovered element plutonium (isotope 239) with alpha particles.

Where is curium found?

Curium does not occur naturally; it is usually artificially produced in nuclear reactors by successive capture of neutrons by isotopes of plutonium and americium.

What is the symbol for curium?

This week, we came across the element curium with the atomic symbol centimeter and atomic number 96. The element is named in honor of Marie and Pierre Curie who discovered the element radium.

What are the 5 elements named after scientists?

Many elements are named after famous scientists. Some of the most famous elements include einsteinium (Albert Einstein), curium (Marie and Pierre Curie), rutherfordium (Ernest Rutherford), nobelium (Alfred Nobel) and mendelevium (Dmitri Mendeleev).
