OK here is the thing I am taking a basic chemistry class and am not sure our instructor knows what she is talking about and neither does the rest of the class.. We have a test next week and are working on Oxidation and Reduction.. When you are assigning O.N numbers to elements how do you figure them out?? I figured the you need to know the possitive and negative charges of all the elements according to the group they are in.. In class she gave us the charges for groups 1A, 2A, 4A, 5A, 6A, AND 7A.. (Which was wrong the first time she gave them to us) She told us that they were going to be the only ones we will need to know but she gave us a take home test and well all the ones from 3B-3A are on the test..

I actually wrote this program when I was a sophomore in high school, which was before I found this site, so the molar masses of individual elements may not reflect the WebElements periodic table exactly. All the same, it's highly accurate.

To operate the calculator, just open the program. The periodic table is set up in the form of buttons, one per element. Click on the button of an element once for each time it is used in a formula, and in a text box at the bottom will be the mass of 1 mole of that substance. Click Clear to clear the box (don't just delete the contents).

In the unlikely case that you use an old (c. 2000) version of Norton or perhaps any version of AVG Anti-Virus, the program may come across as a virus. Ignore it.

The BBC is airing some "periodic tales" on Radio 4. Familiar Radio 4 voices introduce elements from the Periodic Table and the unique roles they play in human existence - with a little help from the irreverent Tom Lehrer. Here is the address to listen in on ten elements:

http://www.bbc.co.uk/radio4/science/periodictales.shtml

Krypton: Heidli Nicklaus on the Superman element, krypton
Helium: Brian Perkins dramatises the effects of Helium.
Silver: Trevor Harrison (Eddie Grundy in the Archers) finds some unusual properties of Silver.
Cobalt: Hedli Nicklaus (Cathy Perks) takes on the goblin element of cobalt.

Ya, I NEED to learn something new about an element, it's for my Physics homework, (don't ask) and I am kinda confused about navigating myself around this forum, so if anyone knows something cool about elements, can you post it here?

Thanks!

is there a web site with heat capacities table? i need to find out a metal with approx. 0.260 j/g*K heat capacity. anybody???

i'm a high school chem. studuent. and i was looking at teh periodic table n the noble gases.

i was wandereing y helium is the only noble gas ending in -ium and all teh rest end in -on.

i noticed it in the alkali metals too(with hydrogen and lithium,sodium,ect.) but MANY of the elements end in -ium

now, my latan isn't too good so i don't know about these suffixs. but if the answer to my question in chemical, plaese help me out. or even if its a language answer to my question

anything would help

What happens to the properties of the elements of the periodic table as you go from left to right?

I'd like to know the recrystallisation temperature of pure metal noble. I don't find them on this site :(, so i'm asking here if someone could help me please. I search it for the nickel, copper, molybdenum, magnesium, aluminium, Ti, Ta, W, Zr, Pa, Zn.
Thank you :)

Does anyone know if referring to an elements "family" is the exact same thing as a "classification?

Any help would be great as I am trying to help my daughter with her science homework.

Thank you

hello!
I need periodic table with electron's coniguration. I look for it on this page and I couldn't find.

Have somebody that table ?
