This is a simple periodic table of the elements, displayed in simple tabular form. Frankly there are much prettier ones on line. But this is the one we currently have in our database and is really here for completeness. That said, it does have one rather nice little feature, insofar as you can group elements together by clicking the column headers.<\/strong><\/p>\n

Units<\/h2>\n

Atomic mass is measured in usually measured in unified atomic mass unit (u). AKA atomic mass units (amu). 1\u2009u is defined as 1<\/sup>\/12<\/sub> the mass of a carbon-12 atom, and is equal to 1.6605\u00d710\u221227<\/sup> kg. <\/span><\/span>Atomic number has no unit. It is simply a number: the number of protons in an atom.<\/p>\n
