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