BC: We have just reviewed the basics of the Periodic Table. Chemistry relies on this table for being able to put elements together and what their calculations will be. That is another section to be reviewed soon. | S8P1. Students will examin the scientific view of the nature of matter. F. Recognize that there are moe that 100 elements and some have similar properties as shown on the Periodic Table of Elements.
FC: Periodic Table Is For Everyone !!!!!!!
2: The table is a detailed list of the elements of the world in an organized fashion Actually, there are over 120 that have been created or found. So we only put the main elements on this table. The elements are put together by periods. The period is where the elements have something in common.
3: Elements that have the same atomic number are in the same row. That is called the atomic orbitals. The elements in the first row have the same number of electrons. For the second row, they each have two electrons. That continues on down until the eight row. The maximum number of electrons is seven so after the seventh row the electrons are all seven.
4: The columns are arranged in a special way. Each column is a group. The group called the orbital electrons have the same number of electrons. The electrons that are the outer ones are the valence electrons.
5: These boxes hold the Noble Gases. The do not need another element to provoke a reaction as other elements require.
6: The two boxes at the top are special. They are Hydrogen and Helium. Hydrogen is sometimes missing an electron and sometimes it has an extra one. Helium can only have two electrons in its outer shell.
7: Finally, we bring you the metals. seventy five percent of the elements are metals. A quick list is actinide, lanthanide, alkali, alkaline-Earth, rare, rare-Earth and transition metals.
