For the last fifty or so years, the periodic table has been incomplete. Elements after uranium on the periodic table have been synthesized for the past few decades, but there were always a few ...

1. Convert kilograms/second to grams per second. 1 kg = 1000 grams. If the mass flowrate is 0.25 kilograms/second, convert ...

The periodic table of chemical elements, often called the periodic table, organizes all discovered chemical elements in rows (called periods) and columns (called groups) according to increasing atomic ...

We see a lot of clocks here at Hackaday, so many now that it’s hard to surprise us. After all, there are only so many ways to divide the day into intervals, as well as a finite supply of geeky ...

When it comes to science, chemistry is elemental. That pun is based on the fact that the main building blocks in the branch ...

This is the second part of a three-part series written by Carolyn Krause. Many of the elements were synthesized using an Oak ...

Nihonium (Nh), a radioactive synthetic element, joined the periodic table of elements in November five years ago with the atomic number 113. More than a century ago, a similar sounding but ...

This year we celebrate the 150 th anniversary of Mendeleev’s achievement in formulating the structure of the periodic table that we use today. He announced his structure in 1869, but the challenge of ...

Cal: OK, friends. Chemistry time and in the studio with me I have super science school teacher Mrs Roberts, who's gonna show us how to make a massive fizzing volcano. We're gonna have sparks, lava ...
