periodic table

• an arrangement of the elements in order of their atomic numbers so that elements with similar properties appear in the same vertical column or group
• a row of chemical elements in order by atomic number
• a column of elements, they are often very similar in how they look and act
• a pure substance made up of only one type of atom
• the number of protons in the nucleus of an atom
