HON CHEMISTRY: You get a bonus! Since I chased so many rabbits over the last few days (and we’ve had icy interruptions!), I went back and found an old vodcast on the p-block elements in just one vodcast. And you get a bonus – it has the f block on it as well!
Be sure and go back and practice getting period, block, group, and type of element from the electron configuration. And don’t forget to go back and look at the nitrogen cycle.Lab tomorrow, and we’ll finish the p-block on Friday.
Speaking of the lab – make sure you have the updated copy of the lab sheets. Read it super carefully – highlight, make notes for yourself, etc. You’re going to need to be moving like a super quick bunny!!

Is Gallium poisonous since it can melt in your hand?
Well i looked it up and my source says it’s not considered toxic but can have some harmful effects if injested. But on another note i found this video that shows a gallium spoon melting in tea!

Wow that was a really cool video! I wish I had some gallium so I could try something like that
The hydrogen video was cool. They blew up a giant balloon with hydrogen and poped it with fire. Big Explosion.
