What are the three types of chemical bonds studied in this text?
The forces that keep atoms together in a molecule or compound are called chemical bonds. The probability of an atom forming a chemical bond with another atom depends on the number of electrons in its outermost orbit, also called the valence orbit. The octet rule helps explain why atoms interact in predictable ways. Ionic bonds are formed when an atom loses or gains one or more valence electrons. Covalent bonds are formed when two or more atoms share electrons. Hydrogen bonds are formed when a hydrogen atom with a partial positive charge attracts the partial negative charge of electronegative atoms. a) I, II, III b) II, IV, V c) III, IV, VI d) I, IV, VI e) II, V, VI
Os três tipos de ligações químicas estudadas no texto são: ligação iônica, ligação covalente e ligação de hidrogênio. A alternativa correta é a letra D) I, IV, VI.
