The choice that is not an example of a molecule is "Mn" which is uppercase M lowercase n.
In order to determine which choice is not an example of a molecule, we need to understand what a molecule is. A molecule is a combination of two or more atoms that are chemically bonded together.
Let's look at each choice to determine if it fits the definition of a molecule:
1. O3: O3 refers to ozone, which is a molecule made up of three oxygen atoms bonded together. Therefore, O3 is an example of a molecule.
2. Uppercase O subscript 3: This notation is the same as O3, representing ozone. So, it is also an example of a molecule.
3. Mn: Mn represents the element manganese. Since it is a single atom, it does not fit the definition of a molecule. Therefore, Mn is not an example of a molecule.
4. Uppercase M lowercase n: This notation does not represent any specific compound or element, as it lacks context. Without more information, we cannot determine whether it is a molecule or not.
5. H2S: H2S represents hydrogen sulfide, which is a molecule made up of two hydrogen atoms bonded to a sulfur atom. Thus, H2S is an example of a molecule.
6. KOH: KOH represents the compound potassium hydroxide, which consists of one potassium atom, one oxygen atom, and one hydrogen atom. It is a molecule as it contains multiple bonded atoms.
Based on the above analysis, option 3 (Mn) is the choice that is not an example of a molecule.
