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.
No. It is a highly unstable element and it is radioactive.
Yes
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.
