To determine the correct answer, we need to understand what a molecule is. A molecule is a group of two or more atoms held together by chemical bonds. Each individual atom in a molecule can be the same or different.
Option 1: "Each atom of a molecule is the same." - This statement is not always true. In a molecule, the atoms can be of the same element or different elements.
Option 2: "All molecules of a compound have one type of atom." - This statement is incorrect. A compound is made up of different elements, so its molecules will consist of different types of atoms.
Option 3: "All molecules of a compound have the same properties." - This is the correct statement. Molecules within a compound contain the same types of atoms and are arranged in the same way, giving them the same properties.
Option 4: "Each molecule of a compound has different properties." - This statement is incorrect. Molecules within a compound have the same properties, as they consist of the same types of atoms arranged in the same way.
