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 __
Periodic Table Basics 1 ________ B 2 ________ 3 _________ P = ____ N= ____ E=____ Step 1. Complete the card for each element. Complete the top section for each element by adding the element’s 1. atomic number 2. name and 3. atomic mass. 4. Determine the number of protons, neutrons, and electrons in each element. 5. Create a Bohr diagram for each element. 5 Boron (10.81)= Application:
Periodic Table Basics Step 2. Use color pencils to shade in the card for each element. not Colored=Hydrogen Green= Li & Na Orange= B & Al Pink= O & S Red= C & Si Blue= Be & Mg Tan= N & P Purple= F & Cl Yellow= He, Ne & Ar
Step 3. Cut the cards apart and arrange according to atomic number in the pattern shown below on a large sheet of construction paper. Step 4. After you have arranged the cards in the correct order, glue them to the paper
