on top of water. Explain this property in terms of hydrogen bonding. Oil molecules cannot form hydrogen bonds with water and thus behave hydrophobically, because there is a prevalence of relatively nonpolar covalent bonds—in this case, bonds between the carbon and hydrogen, which share electrons almost equally. 20.
2-electron, 3-center bond, with bond orders of 1/3. 8.2 He2 + has 2 electrons in the bonding orbital and 1 in the antibonding * orbital, with a bond order of ½. HeH+ has a bond order of one, but with a poorer match between the energy levels of the two atoms (–13.6 eV for H, –24.5 for He). He He2+ He+ He H+ 1s 1s 1s 1s HHe+ 1s* 1s* 1s 1s Electron Configurations and the Periodic Table. Quantum Numbers. To answer this, we need to understand the concept of degenerate orbitals. There is something unusually stable about atoms, such as He and Ne, that have electron configurations with filled shells of orbitals.

The table shows the atomic radius and ionic radius for six metals and six nonmetals. You will use the data to relate the size of an element’s atoms to the element’s location on the periodic table. You also will use the data to compare the sizes of atoms and their ions. 1. Using Tables Within a period, what happens
A covalent bond results when atoms share one or more pairs of electrons. The electrons that are shared in a covalent bond are called bonding • At r3, the atoms are weakly bound together, and the two orbitals overlap one another. Use only a Periodic Table to answer the following questions.form a compound with one phosphate ion. Use the table to help you. a. one b. two c. three Describing Molecular Compounds(pages 174–175) 7. Circle the letter(s) of the information provided by the name and formula of a molecular compound. a. number of atoms in the compound b. number of bonds in the compound c. elements in the compound 8.

© 2014 Pearson Education, Inc. Solid Matter • Solid matter may be crystalline—in which case its atoms or molecules are in patterns with long-range, repeating order.
In metallic bonding a large number of atoms lose their electrons. Ionic bonding is mostly formed between metals located at the left side of the periodic table. Atoms in molecules are held together by the attraction between the nucleus and the shared electrons. Activities Take a ten question quiz about this page. More Chemistry Subjects
