    Here in 'Muricah, we make our own elements!

    if i'm not mistaken... havent we(american) made more new non-natural "elements"?
    also, how is it an element if it's not found in nature?

    In simple terms, lower mass atoms are bombarded with other lower mass atoms in a particle accelerator. Occasionally, the two atoms will actually collide and merge into a new element (because the only thing that defines an atom of an element is the number of protons (and electrons)). Example: you could theoretically make Darmstadtium (Ds/110 protons) you could bombard Lead (Pb/82 protons) with Nickel (Ni/28 Protons). 82+28 = 110 protons.

    This merge does not happen often though. Only a few hundred or thousand atoms will be created. The rest will be deflected. There are not enough atoms to visibly see the element, but enough to measure with special equipment.

    Also, in the case of Darmstadtium, there is a half-life of 11 seconds. This means the nucleus is so unstable that it will decay into two smaller nuclei again (Usually an alpha particle (helium nucleus) and Hs(108 protons)), so much so that after 8 seconds, the mass of Ds will be halved. (eg, if you had 1g of Ds, after 8 seconds, only 0.5g of Ds remains. The other 0.5g are decayed).
    As Ds doesn't last very long, a lot must be produced for a long time to gain a measurable amount.

    Also, in case you were wondering, where i say a few hundred or thousand atoms are made, there are 6.02x10^23 (602,000,000,000,000,000,000,000) in 281g of Ds. Therefore, to make just 1g of Ds, 2.142348754x10^21 atoms would be required (about 2,100,000,000,000,000,000,000). It takes a lot of time and power to make synthetic elements, which is why you can't just make valuable elements like Gold.

    so let me see if my undeveloped mind has this right...

    an element is basically anything that has protons and neutrons... so regardless of its makeup it is an element?

    Pretty much. All atoms are made up of Protons, Neutrons and Electrons. Protons and neutrons make up the nucleus, and the electrons whizz around the outside.

    An "atom" has equal number of protons and electrons. Protons are + charged, Electrons are - charged, hence, atoms are neutrally charged because the charges balance out. If an atom gains or loses electrons, it is referred to as an Ion and not an electron, and it will have a charge depending on the number of electrons it gained or lost.

    Neutrons don't do much in terms of reactions. They do change the weight of the atom (very slightly), and some heavier versions of atoms are unstable and decay radioactively (to become stable). Eg, Carbon-12 and Carbon-13 are stable, but Carbon-14 is unstable and is radioactive. All the Carbons still only have 6 protons and 6 electrons, but the neutrons make the difference in weight. Eg: Carbon-12 = 6p + 6n. Carbon-13 = 6p + 7n.
    The common factor is that Carbon has 6 protons. If it had 7 protons, it would be a Nitrogen atom.

    This makes a huge difference however. Because Nitrogen has just one more proton, to be stable and neutral, it has one more electron. This means there is less space for any other atoms to react with it, so it bonds and reacts completely differently. This results in different properties in all elements. But there are some predictable trends that occur. For example,
    (excluding Hydrogen), everything in group 1 (first COLUMN) is an Alkaline Metal. They are all very reactive, and very soft metals. You can cut through them like butter. On contact with water, they react. As you move down the group, the reactions become more violent.

    Group 8 (18 on this diagram) are all inert. They do not react* at all. Helium will not bond to another element, neither will Neon, or Argon etc. This is why we use these gases in lights - no matter how much you heat them, it won't react with the filament.

    In group 11 of this table, we see Copper, then Sliver, then Gold. (Cu, Ag, Au). It would be predicted that Roentgenium (Rg) would have similar properties to the above metals (such as excellent conductivity, being malleable(bendy)), but we don't know because only trace amounts have ever been made.

    above and beyond, there's my science lesson for the day... now back to videogames and cheetos...

    Heh. Basically same over here, inbetween A-Levels :)

    The good news is you can count those responses as revision.

    I'm surprised Germany wasnt up there more than America

    if you take out the selfmade elements germany has more. And if you dont count in the murica/russia found elements germany has more.
