Hydrogenis the first element on the periodic table, with 1 proton per atom. It's the mostabundant element in the universe. If you look at the Sun, you're mostly looking at hydrogen. Its usual ionization color is sort of a purplish-blue. On Earth, it's a transparent gas, which isn'...

The geometrical forms of the wave functions involved in the binding of atoms enable us to picture the molecules. To illustrate this point, we discuss the ten elements in the first row of the periodic table, from hydrogen to neon, showing how their binding properties (valences) depend on the...
On my Noble Rack page I have all the pictures collected, along with pictures of arcs I made in my other collection of noble gas flasks. This oxygen tube is not installed in the table, because it's so dim you couldn't really see it, and it's said to not last very long. So I ...
Great !!! How can we get plenty of nice, clean non-polluting Hydrogen to run our cars? 1) by cracking hydrocarbons, you know, like petroleum. You just get mounds of sticky, gooey, black stuff (probably toxic) left over, not much good for anything except building roads. ...

The metal is taken to just barely above its melting point, then poured in from close to the water surface, a potentially dangerous operation particularly in the case of aluminum (which can form hydrogen gas that may explode). If the temperature is too high the metal fragments into an almost...
