And where do You have elements with symbols Ch and Es? :)
Can You give me only that two elements instead of whole list (there are no elements with this symbols on Your list) :)

Oops!
Does this help?

The molecular formula of benzene is C6H6, and its empirical formula is CH.

Name: Einsteinium
Symbol: Es
Atomic Number: 99
Atomic Mass: (252.0) amu
Melting Point: Unknown
Boiling Point: Unknown
Number of Protons/Electrons: 99
Number of Neutrons: 153
Classification: Rare Earth
Crystal Structure: Unknown
Density @ 293 K: Unknown
Color: Unknown

Einstenium - right, I forgot about this actinoid.

CH... Empirical formula... Yes, there is something like this, but for benzene it's 'CH' not 'Ch'. And You can use it only in theoretical experiments... If You give it to chemist - he will gentle ask 'what does You mean?'...
Its something like formula of water. You can say it's H2O, but You can also say H6O3 (because of hydrogen bond - water can be in this form).

Benzene, I think may be one of Walt's ingredients. Am I wrong?
Einstenium - I am not sure yet what this is used for.

Hey Walt, are you taking notes on this??? (I remember Bryan Cranston commenting during one of his interviews how he had to learn a portion Chemistry to protray the role of Walt).

error..error, error...spelling of portrayis mispelled...protray is incorrect. Portray is correct.

All right, I'll try again. Algebra was my forte decades ago. Got me out of chemistry, and I don't remember how the pythagoream theory works. That being said, I did hear last week that a new element is in debate for the periodic table. No carbon involved from what I read, and lasts for about 6 seconds in our world. Probably created from those lovely geeks and skanks and whathaveyou whatever minute einstiens who got lots of $ to build the ultimate smasher thingy. Anyway, google it up. There's a new one on the periodic table. Its being debated as to whether it should remain. There's no debate as to its existence. It was matter that was there. They saw it. So it must be.

So I was wrong about the 6 second existence. So its a .0000006 second at best existense. Dang, I'm pretty happy that my post showed up. Anyway, here's the link to the new element.

'Benzene, I think may be one of Walt's ingredients. Am I wrong?

Benzene: it's really hard to get (because of law regulation). and it's cancerogenic. Yes, You can use it, but this way isn't so smart. You need to do other compound from it. But You can buy this compound in shop (cost is about 100x lower).

Einstenium: it's best isotope is stable in 475 days. And it's produced from Uranium (You need to pay really big price to obtain it) So I think it's used only for scientific :)

Benzene is a strange one.. I looked into it a little more... has many uses.
