7. Periodic Table The Periodic Table is a way of listing the. An element is a substance that can’t be broken down anymore. An element is made of kind of atom. Examples: and. Elements are listed in the table by the of their atoms. This includes how many protons they have as well as how many electrons they have in their outer shell. From left to right and top to bottom, the elements are listed in the order of their atomic number, which is the number of protons in each atom. elements pure 1 structure silver oxygen

8. Why is it called the Periodic Table? It is called "periodic" because elements are lined up in cycles or. From left to right elements are lined up in rows based on their number (the number of protons in their nucleus). Groups are the columns of the periodic table. There are columns or groups and different groups have different properties. Study Jams periods atomic 18
