Study Notes
Chemical Families and Ionic Charges
- Groups are arranged in vertical columns
- Alkali metals (Group 1 or 1) have a +1 ionic charge
- Alkaline earth metals (Group 2 or 2) have a +2 ionic charge
- Halogens (Group 17 or 7) are -1
- Noble gases (Group 18 or 8) are 0
Bohr-Rutherford Diagrams
- Diagrams illustrate electron arrangement in atoms
- Examples given include beryllium, lithium, oxygen, nitrogen, and fluoride
Formation of Ionic Compounds
- Chemical reaction between magnesium and nitrogen
- Mg forms a 2+ ion and N forms a 3- ion
- The compound formed is magnesium nitride (Mg3N2)
Ionic Bonding vs. Covalent Bonding
- Ionic compounds form between a metal and a non-metal
- Electrons are transferred
- Opposite charges attract strongly, forming a strong bond
- Ionic compounds are typically hard, brittle solids with high melting points
- Covalent compounds form between two non-metals
- Electrons are shared between atoms
- Covalent bonds are weaker than ionic bonds
- Covalent compounds often exist as gases or liquids, with lower melting points
Chemical Formulas and Names
- Provide chemical formulas and names for various compounds
- Aluminum nitride (AIN)
- Sodium fluoride (NaF)
- Lead (II) iodide (PbI2)
- Copper (I) nitride (Cu3N)
- Iron (II) bromide (FeBr2)
- Potassium bromide (KBr)
- Dinitrogen trioxide (N2O3)
- Calcium phosphate (Ca3(PO4)2)
- Nitrogen tribromide (NBr3)
- And more examples in the text
Types of Chemical Reactions
- Synthesis: Two or more reactants combine to form one product
- Decomposition: One reactant breaks down into two or more products
- Single Displacement: One element replaces another element in a compound
- Double Displacement: Elements from different compounds swap places
Hydrocarbon Combustion
- Complete combustion: Sufficient oxygen produces carbon dioxide, water, and energy
- Incomplete combustion: Limited oxygen leads to carbon monoxide, carbon, and water
Neutralization Reactions
- Acid and base react to form water and a salt
pH Scale
- pH scale measures acidity of solutions
- Scale ranges from 0 to 14
- 0-6 are acids, 7 is neutral and 8-14 are bases
