How do elements form

How can elements properties be predicted? What is a chemical element? What element in the fourth period of the periodic table has 5 valence electrons? How are chemical elements diffrent from chemical compounds? What does organic chemistry study? How do elements change from left to right in the periodic tabale?

One of the habits of scientists is open-mindedness. Scientists need to be receptive to new ideas and suggestions. As new evidence is discovered, new ways of interpreting and understanding it may have to be considered.

To make new elements, scientists borrowed some advice from the heavens.

The transuranium elements elements 95 through were forged by bombarding uranium with neutrons and waiting for the impregnated nucleus to become radioactive and convert its extra neutron into a proton, electron, and a charge-less, nearly massless, antineutrino. But after fermium element , the irradiate-and-wait technique stops working.

Particle physicists "stepped up their game" and upgraded their atomic fodder from neutrons to other elements. The trick was to get the nuclei of the two atoms to fuse into one giant nucleus, generating an entirely unique atom.

Scientists started small—firing helium 2 at einsteinium 99 to beget mendelevium ; launching neon 10 at uranium 92 to engender nobelium Eventually, scientists busted out the big guns and bombarded lead 82 with zinc 30 to beget copernicium and californium 98 with calcium 20 to produce element , provisionally called ununoctium.

But why do scientists succeed where the stars fail? The truth is, the stars don't fail. In the storm of their deaths, some stars probably do forge super heavy elements—even elements heavier than we've created—but these elements don't survive long in the turbulent chaos of a supernova. Super-heavy elements are so fragile they live only a matter of microseconds before they decay into a jumble of atomic scrap metal. There is a limit to the number of protons and neutrons that can squeeze inside an atomic nucleus, but we haven't found it yet.

Protons are positively charged, and because like-charges repel, the protons are in a continuous "this nucleus ain't big enough for the both of us" duel. The neutrons have no charge and quell some of the tension by weaseling between the protons.

The entire nucleus is held together by the strong force—a mysterious force that acts like a bungee cord and pulls everything together. But eventually, the proton's repulsion overwhelms the strong force, and not even the neutral neutrons can prevent the emigration of alpha particles two neutrons and two protons from the nucleus. So the real question is: How big can we go?

As we close the gap between what does exist and what can exist, the laws of physics will eventually stop us from venturing deeper into the world of synthetic matter. Scientists will continue to push the limit of "physically possible," but for now it appears the periodic table is nearing its completion.
