Mendeleev believed that the properties of elements depended on their atomic mass and their periodicity. He noticed that when elements were arranged in order of increasing atomic mass, their chemical and physical properties exhibited a recurring pattern. This led him to formulate the periodic law, which states that the properties of elements are a periodic function of their atomic weights. This arrangement allowed him to predict the existence and properties of undiscovered elements.

The properties of the elements are changed.
The properties of a compound are different from the properties of its individual elements. When elements combine to form compounds, the resulting compound can exhibit entirely new characteristics that are distinct from those of the individual elements.

Atomic Mass.
Mendeleev believed that the properties of elements were based on their atomic weight. He arranged the elements in his periodic table according to their atomic weights, which allowed him to predict the properties of missing elements. This led to the discovery of new elements and the development of the modern periodic table.
the properties of a compound are not the same as the elements that form them.

The properties of the compound will differ from the properties of the elements of which it is made.
The properties of the elements are changed.
A substance that has properties different from the chemical elements in it is a chemical compound. A chemical compound is built from chemical elements that are chemically bonded together. And the "finished product" will have chemical properties that are unique to that compound, and different from the properties of the substances that make it up.
he properties of salts are different from the properties of elements that go into making them
Elements in the same group have similar properties. The groups are made according to the properties of elements. Elements in a group have an equal number of valence electrons.
The properties of a compound are different from the properties of its individual elements. When elements combine to form compounds, the resulting compound can exhibit entirely new characteristics that are distinct from those of the individual elements.
