Review electronegativity of of atoms. Determine differences between metals, not metals and metalloids as determined by their numbers. Outline how to present the correct Lewis Dot formula for a series of listed compounds. List all steps in the procedure for each type of determination.
Discuss how to determine the number of valance electrons in the valence shell in both A group and B group elements. Demonstrate by using a number of elements in the A group and then showing how to correctly determine the valence electron configuration. Show how to indicate the valance electrons for a B group, utilizing period numbers and ssubshell designations.
Review atomic radii changes occurring in groups and periods. Discuss ionization energy as energy required to remove an electron from an atom in the gas phase. Discuss IE changes in atoms as the valence electrons move farther from the nucleus. Use examples to demonstrate and write complete spdf configurations. Define electron attachment enthalpy and affinity. View numbers listed on a chart
Define ionization energy in terms of electron removal from an atom. Discuss energy requirement in order to remove an electron from a valence orbital. Use tables to show ionization energy changes in groups and periods, explain why. Outline magnesium ionization energies,.Explain why only the valence electrons are removed to form an ion and not the core electrons
Discuss how atomic size influences many aspects of chemical properties, including resistance to corrosion and electrical conductivity. Discuss how to determine atomic size based on atomic radius numbers, Show how to determine the atomic radius of a compound from the individual atomic radii. Use examples. Using a table of atomic radii, explain how and why the radius of atoms will increase down a group and decrease across a period. Explain why.
Discuss how atomic size influences aspects of chemical properties, including resistance to corrosion and electrical conduction. Define atomic size and use examples. Determine the radius between atoms in a compound based on their atomic size radius. Using a diagram depicting atomic sizes of atoms, define how and why the radius increases down a group and across a period of atoms in the periodic table. Discuss why the size initially decreases in the transition elements and then increases
