Uranium238
Ununoctium, also known as element 118, is a synthetic element and does not naturally occur in the earth's crust. It is a highly unstable and radioactive element that has only been produced in laboratories.
An isotope is a variant of a chemical element that has the same number of protons but a different number of neutrons in its nucleus. This results in different atomic masses for the isotopes of the same element. Isotopes can be stable or unstable, with unstable isotopes being radioactive and decaying over time. They have various applications in fields such as medicine, archaeology, and nuclear energy.
Radioactive elements are unstable, and the shorter the half-life, the more unstable they are.
Polonium is the element in group 16 that has unstable isotopes. It is a radioactive element with no stable isotopes.
it is unstable and decays to another element
Radioactivity is the property in which unstable nuclei of an element spontaneously emit radiation.
No, americium is an unstable and radioactive chemical element.
