Answer:
For this hands-on portion of the Atomic Structure Lab, students will be deciphering common trends or patterns found within the Periodic Table of Elements. The elements found within the Periodic Table are arranged in a very particular pattern, based on several common traits or characteristics. In 1869, Dmitri Mendeleev produced a table of elements based on their atomic weights. Properties of elements vary “periodically” depending on their atomic weight. Today, the elements of the Periodic Table are arranged by atomic number, which also indicates the number of protons in an atom (see Periodic Table Tutorial above). Neutrons are uncharged particles in the atom’s nucleus that only affect the overall weight of the atom, not the charge. The Periodic Table of Elements is arranged in horizontal rows, called periods and vertical columns, called groups.
