The inner transition metals are radioactive and are found in the f-block. These are commonly referred to as actinoids and are alkali metals.
yes they are. :)
Yes
Metals from the d-block (by opposition with the inner transition metals).
Radioactive elements between transition metals: Tc, Rf, Db, Sg, Bh, Hs, Mt, Ds, Rg, Cn.
incomplete outer shells
Technetium has no stable isotopes.
i think its a main-group element. examples of inner transition metals are U
That is false
You think probable to artificial radioactive elements considered transition metals.
The transition metals, including the inner transition ones.
gold, silver and bronze
Metals are located in the left hand side of the periodic table, non metals are located on the right and metalloids are located in between as a 'bridge'.
