Since 2005, four new elements have been officially added to the Periodic Table: copernicium (Cn, atomic number 112), nihonium (Nh, atomic number 113), flerovium (Fl, atomic number 114), and moscovium (Mc, atomic number 115). These elements were recognized and named by the International Union of Pure and Applied Chemistry (IUPAC) in the years following their discovery.

What are elements that are made in laboratory?
Manmade elements. These have traditionally been considered to be: Technetium, Promethium, Neptunium, and all elements beyond Neptunium. However trace levels of several of these have since then been detected naturally.

What elements have been discovered since newlands' times?
Since John Newlands proposed his octaves in the 1860s, several elements have been discovered, including those in the lanthanide and actinide series, as well as synthetic elements like technetium, francium, and all the transuranium elements up to oganesson (element 118). Additionally, elements such as gallium, germanium, and scandium were identified after Newlands' time. Advancements in nuclear physics and chemistry have led to the synthesis of heavier elements that were not known during Newlands' era.
