All elements have several properties.
properties. Mendeleev's periodic table had gaps for elements that had not been discovered yet, but he was able to predict their properties based on the patterns of the elements surrounding the gaps. This led to the discovery of new elements like gallium, germanium, and scandium.
Mendeleev's periodic table allowed for the prediction of the properties of unknown elements by identifying gaps in the table where elements had not yet been discovered. By examining the properties of neighboring elements, Mendeleev was able to predict the properties of the missing elements and suggest their existence. His periodic table provided a framework for organizing elements based on their atomic mass and chemical properties, which allowed for the accurate prediction of the properties of undiscovered elements.
The properties of a compound are different from those of the elements that make it up. Compounds have unique physical and chemical properties that arise from the way the elements are bonded together, whereas the properties of individual elements are based on their atomic structure. Mixing elements together to form a compound can result in properties that are entirely different from those of the individual elements.
Compounds of different elements can have different properties because their properties are determined by the arrangement and interactions of the atoms within the compound. The types and numbers of elements present in a compound will influence its physical and chemical properties.
Mendeleev arranged the known elements by increasing atomic mass and grouped elements with similar properties together. Gaps in the table indicated elements that were yet to be discovered. By observing the patterns in the properties of known elements within each group, Mendeleev was able to predict the properties of the undiscovered elements that would fill these gaps.
Several characteristic properties include melting and boiling points, density, and reactivity.
they discovers a repeating pattern of properties
Mendeleev was able to predict the properties of the elements that were not discovered at that time. He left gaps for these elements in his Periodic Table.
the properties of a compound are not the same as the elements that form them.
Patterns in the elements’ properties. -Apex
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.
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.
Molecules that contain atoms from several elements for a compound. Examples of these compounds include hydrogen, sodium chloride, methane, and magnesium.
