Matching Pairs Microbiology chapter 2 Online version Chemitstry types of chemical bonds and molecules by misael Lopez 1 nonpolar covalent bond 2 Ionic bond 3 Covalent bond 4 Van der Waals forces 5 Compound 6 Anions 7 Ions 8 Polar covalent bond 9 Hydrogen bonds 10 Molecules 11 Cations - Result from a sharing of electrons - usually the strongest chemical bonds - Positively charged ions - Loss of electron(s) - Weakest of intermolecular forces - Dependent on interatomic distance - Unequal sharing of electrons - Somewhat weaker bond than its counterpart. - Two or more different elements joined together chemically - Equal sharing of electrons - electrons are equally distributed - Negatively charged ions - Gain of electron(s) linkage formed from the electrostatic attraction between oppositely charged ions in a chemical compound - Weak chemical bonds - Always involves a hydrogen atom (+) attracted to an oxygen (-) or nitrogen (-) - Two or more atoms linked by chemical bonds formed by their valence electrons. -Electrically charged atoms, molecules, particles. ~ + or - due to electron loss or gain Redox reactions
