Some can, some cannot
Some physical properties that cannot be seen include density, thermal conductivity, and hardness. These properties can be measured using various instruments and techniques, but they are not visible to the naked eye.
Physical properties are characteristics of a substance that can be observed or measured without changing its composition, such as color, melting point, and density. In contrast, chemical properties describe how a substance interacts with other substances, leading to a change in its chemical composition, such as reactivity with acids or the ability to combust. While physical properties can be seen or measured directly, chemical properties involve potential reactions that may not be immediately observable.
Elements cannot be grouped solely by physical properties because these properties can vary widely within a category, leading to inconsistencies. For example, metals, nonmetals, and metalloids exhibit diverse physical characteristics, such as boiling points, densities, and states of matter at room temperature. Additionally, elements may share similar chemical properties regardless of their physical characteristics, making chemical behavior a more reliable basis for classification, as seen in the periodic table. Thus, grouping by physical properties alone can overlook essential relationships and trends among elements.
is seen when one substance reacts with another substance
The properties exhibited during a substance's transformation to another substance are known as chemical properties. These characteristics relate to the ability of a substance to undergo chemical changes, such as reactivity with other substances or the formation of new compounds.

Chemical energy is stored in the electron cloud.
It is true that a chemical reaction causes a chemical change. An example of this can be seen by adding baking soda to vinegar.

physical properties are those that can be seen or measured without changing a material. chemical properties tell how the substance forms new substances when it mixes with something else.
