Synthetic Element (Periodic Table)

Synthetic Element

The synthetic elements in the periodic table include the 24 chemical elements from atomic number 95 to 118: 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).

The synthetic elements do not occur naturally on earth: they are made either in a nuclear reactor, in a particle accelerator, or by the explosion of an atomic bomb. Hence, they are known as “artificial” or “man-made” elements. The synthetic elements were first created between 1944 and 2010. These elements are unstable, but they decay with different half-lives ranging from a few hundred microseconds to millions of years.
