Rutherfordium is not found in nature. It is a radioactive synthetic element.
Meitnerium is a synthetic radioactive element. It is not found in nature.
Radium
A highly radioactive metal named FRANCIUM was named after France.
The radioactive element that begins with the letter R is radium. Radium is a highly radioactive element and is found in uranium ores. It emits alpha, beta, and gamma radiation.
Yes
No. It is a highly unstable element and it is radioactive.
Francium is radioactive, extremely rare, and was discovered in France (hence the name). It is pretty much useless because of its short half-life and rarity.
non radioactive element
Yes, nobelium is radioactive. It is a synthetic element that does not occur naturally and is produced in laboratory settings. All isotopes of nobelium are radioactive and have short half-lives, making them highly unstable.
Thorium, an element rarely found in some minerals.
Radium is an element; it has no sub-parts. Radium is a radioactive element, so it will slowly and spontaneously decay into other elements.
