Percy Jullian's 115 Birthday is recognized by Google...how COOL is that??
Check out a great video documentary about the life of this influential chemist at http://www.pbs.org/wgbh/nova/physics/forgotten-genius.html
From Friday Virtual Work...."Two unstable elements such as chlorine and sodium can combine and make a stable compound if one wants something the other one doesn't want to have like an extra electron."
Sodium is so highly radioactive, because it has one extra electron, just like the other alkaline metals in its group, that it wants to get rid of. So when it has no other element or substance to give that extra electron away, it becomes very radioactive, and explodes in some substances, for example: Water. ...KCS 6th Graders are AWESOME!
