Hey, I've been given a real ***** of homework and the answer isn't jumping out at me by doing searches on the net. Anyway I have to make element cards. They are basicly cards with information on them about one element. I have to do 4 in total and the questions I need answerd are:

No. of Protons
No. of Neutrons
No. of Electrons
Discoverd In
Discoverd By
3 Uses for the element

Any help would be appreciated.

I would say check your chemistry book.

Find a periodic table. The number of protons and electrons can be found for each element. I believe most tables will also tell you how many neutrons there are.

Better yet, find someone online who will do it all for you!

in the age of the internet, i bet you can "google" all the answers you need.

My major pertains to this subject. However, where would the fun be if I just flat-out told you the answers? You should go to your instructor for extra help, research the info in your book or go to the library. You will no doubt be tested over this stuff later on, yes?

HUMBLE.

P.S.:Master the subject matter, don't let it master you!

I have a vote and I'm not afraid to use it!

As before, Google on the periodic table.

*Each element* has its own specific number of *protons* (each w/ +1 charge) in the nucleus. That equals the number of electrons (-1 charge) orbiting the nucleus. Howver, some elements have more or less neutrons (0 charge) in the nucleus, and they are called isotopes of that element.

In the table, you'll see one smaller number - that is the number of protons, each with a mass of 1 (it was just decided that way).

The number of orbiting electrons is the same as the number of protons. However, electrons have so little mass, it's not counted in the total.

Neutrons have about the same mass as protons.

Atomic mass is proton mass (1) plus nuetron mass (~1) and electron mass not counted.

You'll see a larger number with decimal places afterwards. That is the atomic mass (~ weight). It relates to the *average* mass of the various isotopes of the element. (Just as an aside which may or may not be of interest to you, the distribution of isotopes is very much an Earthside distribution.)

Round that larger number to the nearest whole number to get around the difficulties of dealing with an average. Subtract the number of protons from 'molecular weight' to get the number of neutrons of the most common isotope.

Clear as mud?

And for what it's worth, the people at NIST (National Institute for Standards and Technology - used to be NBS National Bureau of Standards) and others who have to make very, very fine measurements actually worry about getting an 'accurate' average mass on the elements, and whether or not that average has the same isotopic distribution as the particular thing they are measuring.

Well there are at least 4 (maybe even as many as 10) elements that were named after the country they were discovered in. I think (but don't quote me on this) they are in the top row of the 2 rows that are at the bottom of a standard periodic table.

The only element I know much about is the Fifth. She's a gorgeous female-analogue with bright orangey-red hair and really nice teeth. Speaks gibberish in Armenian and looks good in a variety of skin-clinging-type outfits.

I have no idea as to the weight of her various parts or her periods.

Everything I know about the elements I was taught by Venus Fly-Trap.

When faced with a moral question I ask myself; "What would The Lone Ranger do?"

I think Venus played 'The Four Seasons' ... but what did he do about the elements? Inquiring minds want to know!

My knowledge of the elements is mostly alchemical.

The Western (European, and by extension American) elements are Earth, Wind, Water, Fire, and Spirit. Spirit, being the only "mental" element, is the most powerful of the four, and is manifested in all living beings.

In (somewhat lesser-known) Chinese cosmology, there's another system of elements: Fire, Water, Earth, Metal, and Wood.

Sometimes people conflate the two and add Wind to the Chinese system, and merge Earth, Metal, and Wood (since Metal comes from rocks, and Wood grows in earth).

I know this because I use the Element motif in my writing, for the Dragon myth of Creation (each race of dragons has stewardship over one element: Wyrms breath fire, Shen live in rivers, Sphinx live in the desert, and Quetzal have no legs, so must remain airborne). Also, the four elements, in their primal form, worked together to form life (Earth formed a basin to hold Water, Fire [the Sun] stirred Air and created Lightning [a fifth element]. Lightning touched the silty water, and created living cells).

Just the other day, I was interested in knowing if sodium was a metal and I googled to this really cool site:
http://www.chemicalelements.com/
I think it has a lot of what your looking for.

For Inquiring Minds:
On the TV show WKRP in Cinncinati one of the characters named Venus Fly-Trap (played by Tim Reid) helped a gang kid understand the atom by decribingit as a gang neighborhood.
The protons were "the Pros" and the electrons were "the Elected Ones" and so on.
The scene also set up some backstory that Venus was a High School teacher before he became a DJ.

When faced with a moral question I ask myself; "What would The Lone Ranger do?"
