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).
The element in group 4 period 5 is Zirconium (Zr).
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 7 period 5 is element 43, Technetium (Tc). Its chemical symbol is Tc.
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.
non radioactive element
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.
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)
The element in group 4 period 5 is Zirconium (Zr).
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 7 period 5 is element 43, Technetium (Tc). Its chemical symbol is Tc.
