By definition, each element has one more proton than the previous element - so element 1, hydrogen, has one proton in the nucleus, while element 2, helium, has two protons in the nucleus. The periodic table represents elements in their atomic form, where there are an equal number of proto...
But let's suppose you could turn atoms into other atoms very simply. How would you make the first few chemical elements? You'd start with the simplest atom of all, hydrogen (symbol H), which has one proton and one electron, but no neutrons. If you add another proton, another electron...

Helium, neon, argon, krypton, xenon, and radon are the chemical elements from the part of the periodic table that we call the noble gases (once called the "inert gases" because they don't really react that well with other elements). If you think back to your school chemistry, the ...
