Method for determining atom using four-color x-ray equipment

A method for determining an atom using four-color X-ray equipment, comprising:

• inspecting atoms using the X-ray equipment displaying a four-color image and classifying the atoms into a first group to a fourth group by indicating the first group comprising atoms having atomic numbers 1 to 10 in first color, indicating the second group comprising atoms having atomic numbers 12 to 18 in second color, indicating the third group comprising atoms having atomic numbers 20 to 40 in third color, and indicating the fourth group comprising atoms having atomic numbers 42 or more in fourth color on the periodic table, and
• when inspecting a material containing a molecular unit using the X-ray equipment displaying the four-color image, displaying the color of the group comprising the atom having a greatest atomic number among the atoms contained in the material, and determining which group among the first group to the fourth group the atom having the greatest atomic number belongs.
