KOREY TREMBLAY CHEMISTRY Atomic Bonding
Review Protons and Electrons Nucleus Orbitals Atomic Radius
Goals Ability to answer questions about: 1. Electronegativity 2. Lewis Dot Diagrams 3. Different types of Bonding
Electronegativity Atomic radius Electronegativity number
Examples Sodium Chloride – NaCl Magnesium Bromide – MgBr 2
Examples Sodium Chloride – NaCl Magnesium Bromide – MgBr 2 Notice something about these examples?
Ionic compounds “Stealing” of electrons Metal and Nonmetal Electronegativity difference Octet rule
Lewis Diagrams – Ionic compounds Electrons belong only to one atom Each atom is charged Lewis diagram of Water Salt experiment
Covalent bonds Both atoms “share” the electrons Forms a stronger bond Octet rule Oxygen
Lewis Diagrams – Covalent bond Drawing a Lewis Diagram for O 2 Partial Charges (water) Hydrogen bonds
Hydrogen Bonding Based on attraction of charges No electrons are shared or transferred Penny drop experiment
Next week… VSEPR Like charges repel

CHEMICAL BONDING. INTRODUCTION Atoms do not tend to exist on their own Atoms do not tend to exist on their own Most often, they are found joined together,
BONDING The joining together of elements in order to fill their outer shells. CH 4.
Chemistry Daily 10’s Week A mutual electrical attraction between the nuclei and valence electrons of different atoms that binds the atoms together.
How Do We Make Compounds?. What is inside the atom? Atom: made of subatomic particles Proton (+) = atomic # : determines the identity of the element Neutron.
