Document Summary
Ch110 wilfrid laurier university fall 2012: 5. 1 orbital energies, 5. 2 structure of the periodic table, 5. 3 electron configurations, 5. 4 periodicity of atomic properties, 5. 5 energies of ionic compounds - omit, 5. 6 ions and chemical periodicity. 79 orbital a is the same size as orbital c. An ion is a charged chemical species (monatomic or polyatomic) A ion is charged because the number of electrons do not equal the number of protons. An anion is an ion with a negative charge (e. g. cl , o2 , h , s2 , n3 ) A cation is an ion with positive charge (e. g. h+, na+, fe2+, he+) These are groups of atoms in which the total number of electrons do not equal the number of protons. Review of orbital energies for the hydrogen atom (z = 1, 1e atom) The energy of an orbital with principal quantum number is given by. The energy of the orbital increases as n increases (less stable)
