3. Ch. 2-7 Review

4. EXPLAIN the difference between a physical property and chemical property. Provide an example of each. A physical property is the substances physical state- water is a liquid and transparent. A chemical property is the ABILITY of how a substance WILL behave in the presence of another substance- water is not flammable.

5. Place the following from smallest to largest: compound, atoms, elements and mixture. Smallest: Atom which make up elements. Elements bond to make compounds. Compounds/substances can be mixed with other substances to make mixtures.

6. Describe what happens to a sodium atom if we remove: a proton, a neutron and an electron. Sodium has 11 protons, if it lost a proton it would be neon. Sodium has 12 neutrons, if it lost a neutron it would be an isotope of sodium. Sodium has 11 electrons, if it lost a electron it would be a cation having a +1 charge.

8. What happens to the atom size as one moves through a group? Period?  In a group, the number of orbitals increases, thus increasing the atom’s size as you move down.  In a period, the nuclear charge increases as you move across so pulls the valence electrons closer so they atom sizes gets smaller.

9. What happens to the ionization energy as on moves through a group? Period?  In a group, the number of orbitals increases so the energy needed to remove a valence electron is low.  In a period, the number of valence electrons increases so the energy needed to remove a ve- is high.

10. What does electronegativity have to do with ionic bonding?  Electronegativity is the “want” for electrons.  Nonmetals have a high electronegativity, thus gains electrons (from metals) to have a fill orbit.  This transfer of electron(s) occurs during ionic bonding.

12. What is a chemical bond? A force that holds 2 or more atoms together.

13. Why do ions form? They lose or gain electrons to have a stable electron arrangement.

14. What family of elements is relatively unreactive and why? Noble Gases are unreactive because they have a filled valence orbit.

15. Describe the formation of cation and how does this relate to ionization energy? Atoms lose their valence electrons becoming a positive charge because metals (cations) have low ionization energy.

16. Describe the formation of anion and how does this relate to electronegativity? Atoms gain electrons becoming a negative charge because they have high electronegativity “wanting” electrons.

17. Explain the formation of the ionic compound composed of lithium and oxygen. 2 Lithium atoms loses their valence electron becoming +1 charge. Oxygen gains both of those electrons becoming a -2 charge. They fill create a stable orbital arrangement Cancel each other charges out.

18. Provide the 5 properties of an Ionic substance. High melting point Dissolves in water Conductive (after being dissolved in H 2 O) Solids at room temperature Brittle (not malleable)

19. What is the difference between a formula unit, and crystal lattice? Formula Unit is the simplest form of an ionic compound- NaCl. Crystal Lattice is the repeating formula unit forming a lattice. NaClNaClNaClNaCl NaClNaClNaCl NaClNaClNaClNaCl NaClNaClNaCl

20. What is the difference between a monatomic ion and a polyatomic ion? Monatomic ion is a one atom ion. Polyatomic ion is a 2 or more atoms that are covalently bonded that carry a charge.

21. For the following, provide the correct names Fe 2 (SO 3 ) 3 ________________ (H 3 O) 3 BO 3 ________________ Hg 3 (PO 4 ) 2 ________________ Cu 2 CO 3 ________________ Al(NO 3 ) 3 ________________ Iron III sulfite Hydronium borate Mercury II phosphate Copper I carbonate Aluminum nitrate

22. For the following, provide the formula Gallium cyanide Ga +3 CN -1 Ga(CN) 3 Bismuth III chromate Bi +3 CrO 4 -2 Bi 2 (CrO 4 ) 3

23. Iron III hydroxide Fe +3 OH -1 Fe(OH) 3 Hydronium phosphide H 3 O +1 P -3 (H3O)3P(H3O)3P Copper I selenate Cu +1 SeO 4 -2 Cu 2 SeO 4
