The transuranium elements in the periodic table include the 26 chemical elements from atomic number 93 to 118: neptunium (Np), plutonium (Pu), americium (Am), curium (Cm), berkelium (Bk), californium (Cf), einsteinium (Es), fermium (Fm), mendelevium (Md), nobelium (No), lawrencium (Lr), rutherfordium (Rf), dubnium (Db), seaborgium (Sg), bohrium (Bh), hassium (Hs), meitnerium (Mt), darmstadtium (Ds), roentgenium (Rg), copernicium (Cn), nihonium (Nh), flerovium (Fl), moscovium (Mc), livermorium (Lv), tennessine (Ts), and oganesson (Og).
Out of 26 transuranium elements, the first 11 are actinides, and the other 15 are transactinides. All of these elements are unstable, and each of them decays radioactively into other elements.
