Unformatted text preview: MOLECULES • Carbon atoms have four electrons in the outer shell—they can form covalent bonds with four other atoms. FIGURE 2.4 COVALENT BONDING (PART 1) 9 CONCEPT 2.2 ATOMS INTERACT AND FORM MOLECULES • Properties of molecules are influenced by characteristics of the covalent bonds: • These characteristics include: • • • • Orientation Strength and stability Multiple bonds Degree of sharing electrons CONCEPT 2.2 ATOMS INTERACT AND FORM MOLECULES • Orientation—length, angle, and direction of bonds between any two elements are always the same. • Example: Methane always forms a tetrahedron. 10 CONCEPT 2.2 ATOMS INTERACT AND FORM MOLECULES • Strength and stability—covalent bonds are very strong; it takes a lot of energy to break them. • Multiple bonds • Single ‐ sharing 1 pair of electrons • Double ‐ sharing 2 pairs of electrons • Triple ‐ sharing 3 pairs of electrons C‐H C=C N≡N CONCEPT 2.2 ATOMS INTERACT AND FORM MOLECULES • Degree of sharing electrons is not always e...
