New elements on the block
Chemists have officially added four new names for elements 113, 115, 117 and 118 to the periodic table.
Scientists discovered the new elements between 2002 and 2010.
The International Union of Pure and Applied Chemistry officially recognized the discoveries in 2015.
The scientists filled their boxes with the new elements in the periodic table.
Here's where the names come from:
Nihonium (Nh): Japanese researchers named it after the Japanese word "Nihon" -- what Japanese call their island nation.
Moscovium (Mc) and Tennessine (Ts): A team of Russian and United States researchers named Mc after Moscow and Ts after Tennessee.
Oganesson (Og): A Russian team named it after Yuri Oganessian, a famous "element hunter."
