In a lab about the activity series, a solution of copper(II)chloride is placed in a test tube with zinc metal iS If zinc is higher up on the
activity series, it will produce a reaction and replace the copper. Bits of copper are seen in the bottom of the test tube. A good
conclusion would be?

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.
