Answer the following question given this paragraph: Molecular geometry is the three-dimensional arrangement of atoms in a molecule. The molecular geometry, or shape, of a molecule is an important factor that affects the physical and chemical properties of a compound. Those properties include melting and boiling points, solubility, density, and the types of chemical reactions that a compound undergoes. In this lesson, you will learn a technique to predict molecular geometry based on a molecule's Lewis electron dot structure. Q: Molecular geometry is the three-dimensional arrangement of atoms in a what? Choices: - genes - DNA - nucleus - molecule A:
molecule

Answer the following question given this paragraph: Draw the Lewis electron dot diagram for each substance. Double or triple bonds may be needed. Q: What structure shows the bonding between atoms, with dots representing available electrons? Choices: - Mendelian model - Pascal model - string theory - lewis structure A:
lewis structure
