Unformatted text preview: Concept 4.2 Carbon atoms can form diverse molecules by bonding to four other atoms ∙ With a total of 6 electrons, a carbon atom has 2 in the first electron shell and 4 in the second shell. ∙ Carbon has little tendency to form ionic bonds by losing or gaining 4 electrons to complete its valence shell. ∙ Instead, carbon usually completes its valence shell by sharing electrons with other atoms in four covalent bonds. ∙ This tetravalence by carbon makes large, complex molecules possible. ∙ When carbon forms covalent bonds with four other atoms, they are arranged at the corners of an imaginary tetrahedron with bond angles of 109.5°. ∙ In molecules with multiple carbons, every carbon bonded to four other atoms has a tetrahedral shape....
