Classifying the Elements 6.2

Squares in the Periodic Table 6.2 Squares in the Periodic Table The periodic table displays the symbols and names of the elements, along with information about the structure of their atoms. This is the element square for sodium from the periodic table. Interpreting Diagrams What does the data in the square tell you about the structure of sodium atoms?

Electron Configurations in Groups 6.2 Electron Configurations in Groups Elements can be sorted into noble gases, representative elements, transition metals, or inner transition metals based on their electron configurations.

Electron Configurations in Groups 6.2 Electron Configurations in Groups The Representative Elements Elements in groups 1A through 7A: representative elements The group number equals the number of electrons in the highest occupied energy level.

Blocks of Elements 6.2 Transition Elements This diagram classifies elements into blocks according to sublevels that are filled or filling with electrons. Interpreting Diagrams In the highest occupied energy level of a halogen atom, how many electrons are in the p sublevel?
