Name: __________________ Date: _____________ Period: ___________ Name: Hour: Date: Bohr Model Practice For each element, write the total number of electrons on the line. Then color the correct number of electrons for each orbit. Remember, fill the orbit closest to the nucleus first, but never exceed the number each orbit can hold. Check the Periodic Table to find out how many electrons each element actually has. Sodium (Na) _________ Potassium (K) ________ # electrons Hydrogen (H) ________ Carbon (C) _______ Oxygen (O) ________ Silicon (Si) ________ Arsenic Iodine(As) (I) ________ Chlorine (Cl) ________ Bromine (Br) _______ Argon (Ar) ________ Magnesium (Mg) ________ Calcium (Ca) ________ Part 2. Now draw your own models for the atoms below. INCLUDE NUCLEUS PROTONS AND NEUTRONS Now THE draw your own BohrWITH model diagrams for the following atoms: (Example: 19P, 20N) Find mass on the periodic table (round to nearest whole number) Lithium (Li) ______ Protons: Neutrons: Electrons: Sulfur (S) ______ Protons: Neutrons: Electrons: Neon (Ne) ______ Protons: Neutrons: Electrons:
