Unformatted text preview: Ionic bonding attraction between ions. Sodium can lose 1 electron chlorine can gain 1 electron. Sodium becomes a + ion. Chlorine becomes a - ion. Table 2-2, Figure 2-3, p. 25-26 Covalent Bonding: Atoms share electrons to fill outermost shell. Single Covalent Bond 1 Pair Electrons Double Covalent Bond 2 Pair Electrons Triple Covalent Bond 3 Pair Electrons Figure 2-4, p. 26 Non-polar Covalent Bonds Atoms share electrons equally. Hydrogen Gas (H-H), Methane (CH 3 ) Figure 2-4, p.26 Polar Covalent Bonds Electrons spend more time around one atom and less around another. Figure 2-4, p. 26 Hydrogen Bonds Polar molecules carry slight charges Electrons favor one atom over another. Hydrogen bond forms between + end of one molecule and - end of another.
