How are the elements on the periodic table organized?
How can the number of protons, electrons and neutrons be determined for a
given atom using the Periodic Table?
Periodic table, Period, Group, Family, Atomic number, Atomic Mass
Goals




Explain how elements are arranged in order of atomic number, usually in rows, so
that elements with similar atomic structure (and hence similar chemical
properties) appear in vertical columns.
Define & describe how periods and groups are also used to organize the periodic
table.
Define atomic number & mass number.
Determine the number of protons, electrons and neutrons for a given element
using its atomic number and atomic mass.
