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