Answer:
Different substances have different properties because they are made up of different types of atoms or molecules, which interact with each other in unique ways. For example, the properties of water are very different from those of sulfuric acid, because water is made up of hydrogen and oxygen atoms, while sulfuric acid is made up of sulfur, hydrogen, and oxygen atoms.
The properties of a substance are determined by various factors, such as the type and number of atoms or molecules in the substance, their arrangement, and the strength of the chemical bonds between them. For example, the strength of the bonds between the atoms in a substance determines its melting and boiling points, while the arrangement of the atoms or molecules determines its crystalline structure.
Moreover, the electrons in the atoms or molecules play a crucial role in determining the properties of a substance. The way in which the electrons are distributed around the atoms or molecules affects their reactivity, polarity, and other characteristics. For instance, substances that contain polar bonds tend to have different physical and chemical properties from those that have non-polar bonds.
In conclusion, the unique combination of atoms or molecules, their arrangement, and the strength and nature of the chemical bonds between them, as well as the distribution of electrons, are the main factors that determine the properties of different substances.
