What type of metal is ununtrium?
It is supposed that ununseptium is a halogen (non metal).
Because francium breaks down and gives off particles and energy it is a what?
Francium is a radioactive chemical element an can disintegrate.
Which element is radioactive and synthetic?
Plutonium is a synthetic element that is radioactive. It does not occur naturally in nature and must be artificially produced through the nuclear fission of uranium.
First element known to be radioactive?
Uranium is the first element known to be radioactive. It was discovered by Henri Becquerel in 1896.
Any element with an atomic number greater than 92 is?
An element with an atomic number greater than 92 is considered a transuranium element. These elements are artificially created in a laboratory and are generally unstable, undergoing radioactive decay. Examples include neptunium, plutonium, and americium.
Is lead radioactive?
Yes, lead is a stable element and is not considered radioactive.
Is ununpentium a metal?
Yes, ununpentium is a synthetic element that falls under the category of metals. It is a highly radioactive element and its properties are not well-known due to its short half-life.
What type of metal is ununtrium?
It is supposed that ununseptium is a halogen (non metal).
What does it mean if an element is radioacitive?
If an element is radioactive, it refers to the stability of their atomic nucleus. If that atomic nucleus is not stable, it is considered radioactive.
Why is uranium considered radioactive?
Uranium is considered a radioactive chemical element because uranium (all the isotopes) is unstable and emit nuclear radiations.
Is the element thulium radioactive or non-radioactive?
Thulium is a non-radioactive element. It is part of the lanthanide series on the periodic table and has no stable isotopes that are radioactive. Thulium-169, the most common isotope, is stable and does not undergo radioactive decay. Therefore, thulium is considered non-radioactive.
Because francium breaks down and gives off particles and energy it is a what?
Francium is a radioactive chemical element an can disintegrate.
Is the element sodium radioactive or non-radioactive?
non radioactive element
Is the element hassium harmful?
Yes, hassium is a highly radioactive element and is considered to be harmful to human health due to its toxicity and potential for disrupting cellular processes. Exposure to hassium should be avoided.
Is seaborgium a metal or nonmetal?
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.
How do you use radioactive element in a sentence?
A radioactive element is one that discharges radiation. Uranium is a radioactive element. A radioactive element is very dangerous if you don't have protective clothing. You should never go near a radioactive element.
What characterizes a radioactive element?
A radioactive element is characterized by having unstable atomic nuclei that decay and emit radiation in the form of alpha particles, beta particles, or gamma rays. This decay process results in the transformation of the element into a different element or isotope.
