Rank the following elements according to their ionization energy: 1. Aluminum 2. Oxygen 3. Fluorine 4. Sulfur The Correct Answer and Explanation is: The ionization energy of an element refers to the amount of energy required to remove an electron from the outermost shell of an atom in its gaseous state. Ionization energy typically increases

Starches are A neither polymers nor monomers B polymers C both polymers and monomers D monomers The correct answer and explanation is: The correct answer is B. Polymers. Starches are classified as polymers because they are made up of repeating subunits called glucose molecules, which are linked together through glycosidic bonds. These glucose units, which
