  • Chapter 6- The Periodic TableVocabulary-Atomic Mass, Atomic number, macronutrient, trace element, trace amount, periodic table, periodic properties, electronegativity, ionization energy, orbital, transition metal, noble gas, alkali metal, alkali earth metal, atomic radius, valence, electron shell, electron configuration, bonding, Lewis dot diagrams

  • The state says you need to 3.01 Analyze periodic trends in chemical properties and use the periodic table to predict properties of elements.Groups (families).Periods.Representative elements (main group) and transition elements.

  • MoreElectron configuration and energy levels.Ionization energy.Atomic and ionic radii.Electronegativity.

  • New way to examineChm.1.3 Understand the physical andchemical properties of atomsbased on their position in thePeriodic Table.

  • Chm.1.3.1 Classify the components of a periodic table (period, group, metal, metalloid, nonmetal, transition).Chm.1.3.2 Infer the physical properties (atomic radius, metallic and nonmetallic characteristics) of an element based on its position on the Periodic Table.

  • Chm.1.3.3 Infer the atomic size, reactivity, electronegativity, andionization energy of an element from its position in the Periodic Table.

  • What is the universe made of?

    The materials the universe first developed were few, mainly hydrogen and heliumWhere did the rest come from?(explain the process of fusion that happens in stars)Pressure causes nuclei to fuse together

  • The periodic tableGregor Mendeleev notice patterns in the mass and reactions of elements (Scientists notice patterns and anomolies)Periodic means repeating

  • Size of atoms

  • The Strong nuclear force keeps the protons and neutrons together. The more protons and more neutrons you have, the stronger the attraction between the nucleus and the electrons.This is what makes the atom radius smaller as you cross the periodic table.

  • ElectronegativityElectronegativity is the measure of how well an atom can attract electrons from another atom to which it is bonded.They are already bonded...what does it do to the electrons. The more electronegative it is, the more likely it is to pull off electrons of its partner.

  • Ionization energyionization energy - the energy required to remove an electron from its atom.Almost, but not quite like electronegativityElectronegativity is how well it takes someone elses electronIonization energy is how well it holds on to its own electrons

  • 6.2 Properties of groupsColumns on the periodic table are called groups or families. Each member of the group would have the same number of electrons in the outside orbital. Thus, they would be similar chemically

  • Group I- Alkali Metals(Hydrogen not actually considered a part of it)Soft Metals. lose the one electron on its outer orbital easily. React explosively with water.In your body used in nerve signaling. (electrolytes)

  • Group II-Alkaline Earth metals2 outer electrons, they lose them easily (ions are B 2+ , Ca 2+ , etc)CaO, CaCl2, etc

  • Transition MetalsThe low part of the periodic tableOuter electrons are in the d orbitalCan bond in different ways, both FeO and Fe2O3.Traditional metals, good conductors of electricity

  • Carbon, Nitrogen, OxygenVery flexible in bonding, especially carbon4, 5, and 6 electrons in their outer orbitals

  • HalogensGroup 177 of 8 possible electrons in the outer orbitalTend to pull an electron off another atom to form ionic bonds. Form diatomic molecules (F2, Cl2, etc.)Form acids with H (HCl, HBr, HF)Form salts with metals (NaCl)

  • Noble GasesDont normally form bonds!Outer orbitals are full!~

  • CompoundsCompounds give each participating atom a full outer orbital. This makes it more stable.CH4, H2O

  • Section 6.3 ValenceReactions only occur in the highest unfilled electron level.Atoms react to have a full or empty outer levelThe total possible valence electrons is 8Each group or family has the same number of electrons in every members outer shell.

  • Lewis DotsLewis Dots represent the number of electrons in the outer orbits. These electrons are referred to as Valence electronsNotice that each family looks the same in Lewis DotsYou need to be able to make Lewis dots for each group or family

  • NotesMake sure you read 189 to 191

  • Faculty Periodic TableArrange at least 30 of the staff at Paisley into a periodic table.Remember that Periodic means having patterns.Explain your reasoning for your arrangement (75%)Creativity with symbols and appearance is appreciated (25%)

  • IncludedReason for groups (10 pt)Reason for families (10)At least two other periodic traits (10)Creativity and appropriateness (10)
