Bohr's atom model
Neil Bohr Atom model To build this you need - wooden board ( we used our broken taekwondo boards) Draw Bohrs atom shells and orbitals on the board with a pencil Method 1: Drill some toothpick size holes and insert toothpicks and cut them and make sure they are atleast 2cm. Method 2: Use drill bit to carve some holes - Use christmas ornaments for Nucleus. Method 1: Use beads with holes to represent Neutrons, Protons and Electrons. Method 2: You can use chinese checker board balls as well. Example. Sodium : 11 protons , 11 neutrons and 11 electrons Nucleus : Black beads - 11 represents protons Yellow beads - 11 represents Neutrons Electrons: Based on Aufbau principle, Hund rule and Pauli exclusion - K shell - s orbital - 2 electrons of opposite spins - L shell - s orbital - 2 electrons of opposite spins - L shell - 6 p orbital of opposite spins - M shell - 1 electron in s orbital
