Since I finished school, the Mendeleev table has significantly transformed: at least ten new elements have been added. Importantly, they are easy to remember – especially those at the end of the list:
Hassium (1994)
Darmstadtium (1994)
Roentgenium (1994)
Copernicium (1996)
Flerovium (1999)
Livermorium (2000)
Ununoctium (2002), might become Oganesson
Ununtrium (2003), might become Nihonium
Ununpentium (2003), might become Moscovium
Ununseptium (2010), might become Tennessine
But what particularly fills me with pride is that nearly all of them were discovered in two places, half of the list in Germany, at the Center for Heavy Ions, the other half in Dubna.
