Is it possible to predict physical properties?

Although chemical properties obey the periodic law, it is impossible to predict physical properties of elements based on their location in the periodic table.

Can chemical properties be identified by the changes they produce?

Chemical properties are very useful in identifying substances. However, unlike physical properties, chemical properties can only be observed as the substance is in the process of being changed into a different substance.

Can matter be identified by its physical and chemical properties?

All properties of matter are either physical or chemical properties and physical properties are either intensive or extensive. Physical properties can be measured without changing a substance’s chemical identity. Chemical properties can be measured only by changing a substance’s chemical identity.

How could modern scientists use the periodic table to predict the properties of newly synthesized elements?

The Periodic Table can predict the properties of new elements, because it organizes the elements according to their atomic numbers. They hope that the two nuclei at the centre of these atoms will fuse and form a heavier nucleus. When these heavy elements form, they are usually highly unstable.

Can you predict the properties of a compound by knowing the properties of the elements that make up the compound explain your answer?

Can you predict the properties of a compound by knowing the properties of the elements that make up the compound? No, the properties of a compound are usually different from the properties of the elements that make up the compound.

How can a chemical property of a substance be identified?

The chemical properties of a substance can be determined by performing experiments that use specific materials or processes with known characteristics. If a material affects the substance in a given way, the substance has a particular property. If a process changes the substance, more properties can be deduced.

Which of the following would result in new substances with new properties?

The chemical reaction produces a new substance with new and different physical and chemical properties. Matter is never destroyed or created in chemical reactions. The particles of one substance are rearranged to form a new substance. The same number of particles that exist before the reaction exist after the reaction.

Which of the following can be observed without changing the chemical makeup of a substance?

Physical properties
Physical properties are properties that can be measured or observed without changing the chemical nature of the substance. Some examples of physical properties are: color (intensive)
