Periodic Table Arrangement Periods Groups Vertical columns are called GROUPS or FAMILIES; there are 18 groups Horizontal rows are called PERIODS; there are 7 periods Practice

Groups Elements in the same group have the same number of electrons in the outer shell (this correspond to their group number) (Most important) All of the elements in the same group have similar PROPERTIES Groups

Periods As you move across through the periods an extra electron is added: E.g. :  Lithium has 3 electron in the configuration 2,1  Beryllium has 4 electron in the configuration 2,2  Boron has 5 electron in the configuration 2,3

Periodic Properties  Atomic Size: determined by the size of the outermost occupied orbital.

Practice 1. Nitrogen: name the period_____ ; group __. 2. Calcium: name the period___ ; group __. 3. Silicon: name the period___ ; group __. 4. Carbon: name the period___ ; group __. 5. Chlorine: name the period___ ; group __. 6. Potassium: name the period___ ; group __
