The periodic table tells a lot of what you need to know about each element, including the number of electrons, protons and neutrons. Take a look at the periodic table entry for carbon (see the Resources section). What information does the entry for carbon give you?
example,carbon atomsalways have six protons;hydrogen atomsalways have one; andoxygen atomsalways have eight. Different versions of the same element, called isotopes, can have a different number of neutrons. Elements can also gain or lose electrons to become charged, in which case they are called...
