Henry Moseley was an English physicist who had a major impact on our understanding of what an atom of an element is made of and how we should arrange these elements in the periodic table, and doing all of this before he was killed in action in the First World War at only 27.
The International Union of Pure and Applied Chemistry, better known by its acronym IUPAC, has announced that four new elements 113, 115, 117 and 118 will receive their permanent seats at the Periodic Table, thereby completing the heretofore incomplete seventh row.

"People call me Cos, so my favorite element is osmium. It's just like one letter away from being Cosmium," he said. This
Experts may have all the answers, but let's face it: kids have all the best questions. Today, 10-year-old Cosmos shares his passion for the periodic table of elements.

The periodic table of the elements has grown ever since the first version was published by Dmitri Mendeleev in 1869. And
Today we talk about chemical reactions occurring not only here on Earth, but even in the interstellar medium. We may have lost the naïve simplicity, but we have gained the understanding, precision, and predictive power.
