Chemistry
I don't get chemistry at all!
Just one quesion!
Why aren't there any ionic elements?
thanks.

Maybe give some free advice about: School?
here's the best i can explain it: an element is a pure thing with a set number of protons, neutrons, and electrons. for an element to become an ion, it has to either gain or lose electrons. so, for example, if you have an ion of hydrogen, it would have one more electron than the pure hydrogen element. so if you had a hydrogen molecule with one proton, one neutron, and one electron, it would be a molecule of pure hydrogen. if you had a hydrogen molecule with one proton, one neutron, and two electrons, it would be a hydrogen ion (which would also give it the noble gas electron configuration of helium). so, if we tie that in with how the periodic table is arranged... okay, the table is in order of atomic number, which is also the same as the number of protons in the element. so, as the atomic number increases by one as we go from element to element, the number of protons increases by one, and the number of electrons also increases by one. so, going with that, hydrogen has one proton and one electron, and helium has two protons and two electrons. so a hydrogen ion (which has two electrons) would have the same electron configuration as the noble gas helium (which also has two electrons). i hope i helped :)

Elements are stable (unless radioactive), and for atoms to be ions, they must gain or lose electrons. Ions are found in compounds as positively and negatively charged atoms of different elements, and they combine to stabilize, forming the compounds. Message me with any other chem questions, I study AP chem. :)
