technetium (Te)
The halogen in period 6 is astatine. It is a radioactive element and is the rarest naturally occurring halogen on Earth.
The element in group 18 period 5 is Xenon (Xe).
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.
The element in group 4 period 5 is Zirconium (Zr).
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.
Dubnium is an artificial chemical element, metal, solid, radioactive, placed in period 7 and group 5 of the periodic table of Mendeleev.
uranium get d fastest decay period
Yes, the period of an element is the time it takes for half of a radioactive isotope to decay, also known as the half-life. During this time, half of the radioactive atoms in a sample will undergo radioactive decay, transforming into different elements or isotopes.
Dubnium is an artificial chemical element, metal, solid, radioactive, placed in period 7 and group 5 of the periodic table of Mendeleev.
A radioactive element in period 6 of the periodic table is Polonium (Po). It is a highly radioactive metal with no stable isotopes. Its most stable isotope, Polonium-210, has a half-life of about 138 days.
non radioactive element
The halogen in period 6 is astatine. It is a radioactive element and is the rarest naturally occurring halogen on Earth.
The element in group 18 period 5 is Xenon (Xe).
There is no element that has been found yet with those characteristics ( group 5, period 2)
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.
