  1. ____ bonds form between metal and nonmetal atoms.
  2. When an atom gains or loses electrons and becomes charged, it forms a(n) ____.
  3. ____ bonds form between nonmetal atoms.
  4. Ions form a structure called a crystal ____.
  5. Atoms that share electrons form a structure called a(n) ____.
  6. Ionic compounds ____ in water to become charged ions.

Verified Answer :

  • Assign "Ionic" to bonds between metal and nonmetal atoms.
  • Identify "Ion" as a charged atom resulting from electron gain/loss.
  • Assign "Covalent" to bonds formed between nonmetal atoms.
  • Identify "Lattice" as the ordered structure formed by ions.
  • Assign "Molecule" to the structure formed by sharing electrons.
  • Identify "Disassociate" as the process ionic compounds undergo in water.
  • Final set: \(\boxed{1. \text{Ionic, } 2. \text{Ion, } 3. \text{Covalent, } 4. \text{Lattice, } 5. \text{Molecule, } 6. \text{Disassociate}}\).

Explanation

  1. Problem Analysis

The problem asks us to classify six chemical concepts using the following six terms: Covalent, Ion, Lattice, Disassociate, Ionic, and Molecule. Each term must be used exactly once to complete the six sentences provided. We must analyze the fundamental definitions of chemical bonding and structure to correctly place each term.

  1. Evaluating the Sentences
  2. Sentence 1: "____ bonds form between metal and nonmetal atoms." Metal and nonmetal atoms typically interact via the transfer of electrons, resulting in the formation of ionic bonds. Thus, the missing word is "Ionic".
  3. Sentence 2: "When an atom gains or loses electrons and becomes charged, it forms a(n) ____." A charged particle that results from the gain or loss of electrons is called an ion. Thus, the missing word is "Ion".
  4. Sentence 3: "____ bonds form between nonmetal atoms." Bonds between nonmetal atoms involve the sharing of electrons and are called covalent bonds. Thus, the missing word is "Covalent".
  5. Sentence 4: "Ions form a structure called a crystal ____." In ionic solids, ions are arranged in a highly ordered, repeating three-dimensional array known as a crystal lattice. Thus, the missing word is "Lattice".
  6. Sentence 5: "Atoms that share electrons form a structure called a(n) ____." A structure composed of atoms held together by covalent (shared-electron) bonds is called a molecule. Thus, the missing word is "Molecule".
  7. Sentence 6: "Ionic compounds ____ in water to become charged ions." When ionic compounds are placed in water, the crystal structure breaks apart into individual ions, a process known as dissociation. Thus, the missing word is "Disassociate".
  1. Verification and Conclusion

We have used all six words from the provided list (Ionic, Ion, Covalent, Lattice, Molecule, Disassociate) exactly once. The sentences now read correctly according to chemical theory:

  1. Ionic bonds form between metal and nonmetal atoms.
  2. When an atom gains or loses electrons and becomes charged, it forms an ion.
  3. Covalent bonds form between nonmetal atoms.
  4. Ions form a structure called a crystal lattice.
  5. Atoms that share electrons form a structure called a molecule.
  6. Ionic compounds disassociate in water to become charged ions.

Examples

Understanding chemical bonds is essential in everyday life. For example, the salt you put on your food (sodium chloride) is an ionic compound that forms a lattice structure and disassociates when you add it to boiling water for cooking pasta. Meanwhile, the water molecule itself consists of oxygen and hydrogen held together by covalent bonds. By identifying these structures, we can predict how substances interact with each other in cooking, medicine, and environmental science.
