CHAPTER 7 READING GUIDE – IONIC COMPOUNDS AND METALS 1. A _____________________ bond is the force that holds two atoms together. 2. Chemical bonds can form by the attraction between the ______________ nucleus of one atom and the __________________ electrons of another atom, or by the attraction between positive ____________ and negative _____________. 3. An ______________-_________________ structure is a type of diagram used to keep track of ____________________ electrons. 4. A ____________________ ion forms when an atom loses one or more valence electrons in order to attain a ______________ gas configuration. 5. By losing an ________________, the sodium atom acquires the stable outer-electron configuration of ______________. 6. It is important to understand that although ________________ now has the electron configuration of __________________, it is not neon. 7. ______________ atoms are reactive because they lose valence electrons easily. 8. The group _________ and __________ metals are the most reactive metals on the periodic table. 9. Although the formation of an ________________ is the most stable electron configuration, other electron configurations can provide some ________________. 10. ____________________, which are located on the right side of the periodic table, easily gain _________________ to attain a stable outer electron configuration. 11. An ________________ is a negatively charged ion. 12. The ________________ force that holds oppositely charged particles together in an ionic compound is referred to as an ____________________ bond. 13. Many ionic compounds are ________________, which means that they contain only two different elements. 14. The __________________ bonds in a compound determine many of its ____________________. 15. The strong attractions among the _________________ ions and the __________________ ions in an __________________ compound result in the formation of a ___________________ lattice. 16. _________________ point, __________________point, and ___________________ are physical properties of matter that depend on how strongly the particles that make up the matter are __________________ to one another. 17. _________________ are charged particles, so whether they are free to move determines whether an ionic compound conducts ____________________. 18. Both _________________ compounds in solution and in the liquid state are excellent conductors of _____________________. 19. An ionic compound whose aqueous solution conducts an electric current is called an ______________________. 20. Ionic crystals have ____________ melting points and _______________ boiling points. 21. During every chemical reaction, energy is either __________________ or ______________________. 22. If energy is absorbed during a chemical reaction, the reaction is _______________________. If energy is released, it is ____________________. 23. Because chemists around the world need to be able to communicate with one another, they have developed a set of rules for __________________ compounds. 24. A ___________________ ion is a one-atom ion such as ________ or _________. 25. The charge of a monatomic ion is known as its ____________________ number, or oxidation state. 26. The __________________ number of an element in an ionic compound equals the number of ____________________ transferred from the atom to form the ion. 27. In the chemical formula for an ionic compound, the symbol of the ________________ is always written first, followed by the symbol of the __________________. 28. __________________, which are small numbers to the lower right of a symbol, represent the number of ______________ of each element in an ionic compound. 29. Many ionic compounds contain ___________________ ions, which are ions made up of more than one atom. 30. Because a polyatomic ion exists as a unit, never change ________________ of the atoms within the ion. 31. If more than one polyatomic ion is needed, place _____________________ around the ion and write the appropriate subscript outside the parenthesis. 32. ___________________ often form lattices in the solid state. 33. The _______________ sea model proposes that all the metal atoms in a metallic solid contribute their __________________ electrons to form a sea of electrons. 34. A _________________bond is the attraction of a metallic cation for delocalized electrons. 35. In general, _______________ have moderately high melting points and high boiling points. 36. Metal are ______________________, which means they can be hammered into sheets, and they are __________________, which means they can be drawn into wire. 37. The movement of mobile __________________ around positive metallic cations makes the metals good ___________________. 38. An _______________ is a mixture of elements that has metallic properties. 39. _____________ steel, ________________, and cast ________________ are a few of the many useful alloys.
