These are true and false questions and I want to be sure of my answers. Please someone check. Thanks:
The eight-element periodicity found in the Periodic Table is related to the number of electrons in the outermost energy level of the atoms that make up each element. True
2. Electrons in the first energy level of an atom are called valence electrons. False
3. For atoms important to life, if the first energy level is the outermost shell, it is stable with 2 electrons. If any other energy level is the outermost shell, it is stable with 8 electrons. True
4. Atoms tend to react in ways that give each atom a stable outer shell of electrons. True
5. Atoms with an outer shell that is almost empty are located on the right side of the Periodic Table while atoms with an outer shell that is full or almost full are located on the left side of the Periodic Table. False
6. Atoms in the same row of the Periodic Table tend to have the same number of valence electrons. False
