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