WebThis periodic table of the elements with names, atomic number, symbol and mass is color-coded for easier reference by students and researchers. For quick reference, go to the periodic table chart with names listed alphabetical order. Click the image to download and view the periodic table of the elements. WebWhen we look at an atom, we find that it has the same about of protons as it does electrons. So, if we look at oxygen, we see that its atomic number is 8, meaning that it has 8 protons. We can also assume that it has 8 electrons. So, oxygen has eight positive particles plus eight negative particles. Think of this as 8+ (-8) or 8-8. nahm forms
