In the lab, a student measures a cube of copper to be 2.25 cm on a side. What is the volume of the cube, with the correct number of significant digits and units? When entering your answer, make sure that there is a single space between your numerical value and your unit: "12.34 mL".

Identify one disadvantage to each of the following models of electron configuration: -dot structures -arrow and line diagrams -written electron configurations type in your answer below. (answer) -dot structures do not show the distribution of electrons in orbitals and take up a lot of space. -arrow and line diagrams take up a lot of space and make it difficult to count electrons. -written configurations make it easy to lose count of electrons and do not show the distribution of electrons in orbitals.
