The elements of a compound combine to form new substances with properties that are different from the individual elements. This is due to the chemical bonds that form between the elements, resulting in unique physical and chemical characteristics for the compound. The properties of a compound are determined by the type of elements present, as well as the arrangement and strength of the chemical bonds within the compound.

Why did mendeleev leave blank spaces on his periodic table?
Mendeleev left blank spaces because certain elements on the Periodic Table were not known at that time. He knew that in the future, those elements would be found and placed on the periodic table.
How could Mendeleev make predictions about the properties of undiscovered elements?
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.
What are the two especially important properties that Dmitri mendeleev noted about the elements?
Dmitri Mendeleev noted that elements displayed periodicity in their properties, with similar properties occurring at regular intervals when elements were arranged in order of increasing atomic mass. He also recognized that there were gaps in the sequence of known elements, which led him to predict the properties of undiscovered elements.
Do an elements properties change when it combines with another element?
The chemical properties of atoms are significantly changed when they form compounds. When elements combine to form compounds it is called a chemical reaction. The compound is then a collection of molecules and each molecule has in it atoms from the elements used in the formation. The atoms in the molecule are still the same atoms as one started with, but the arrangement of the electrons in the atoms has changed. It is the electronic properties of atoms and molecules that really determine the properties they have and which chemical reactions occur and which do not. The chemical properties of an atom or molecule are determined by the arrangement of the electrons of that atom or molecule. Once atoms have gone through a chemical reaction, the electronic structure is changed. The atoms are the same identity, but the properties of the atoms have been changed by the chemical reaction.
What was the importantance of mendeleeve's periodic table to chemists?
Mendeleev's periodic table was important to chemists because it organized the elements based on their properties and atomic masses, allowing for predictions of the properties of undiscovered elements. This helped fill gaps in the table and led to the discovery of new elements. It also provided a framework to understand relationships between elements and their chemical behavior.

Is it correct to write - This issues with the approval of XYZ?
That is a simply awful construction. Some revisions: This <fill in the blank> has been approved by XYZ. This <fill in the blank> has been authorized by XYZ. This <fill in the blank> has been issued under the authority of XYZ. This <fill in the blank> is issued and authorized by XYZ. Or perhaps you meant: Pending the approval of XYZ, this <fill in the blank> will be issued.

Why was the pattern that newlands developed called the law of octaves?
his tables contained gaps that elements with particular properties should fill.
