- There are seven horizontal rows of the periodic table, called periods.
- The length of each period is determined by the number of electrons that are capable of occupying the sublevels that fill during that period.
- Each set of elements has its unique set of properties, with different sets of elements having some common characteristics in terms of electron arrangements.
- We can see patterns of electronic structure and reactivity that allow us to understand better the behavior of individual elements.
- Based on electron configurations, the table can be divided into blocks denoting which sublevel is in the process of being filled.
