Why did Dimitri Mendeleev predict that more elements with specific properties would be discovered?
because,he predicted some possible chemical formulas of the then undiscovered elements between the elements in his Periodic Table. so he concluded that more elements with specific properties would be discovered.
What else can I help you with?
Why did Dmitri leave blank on the preodic table?
There is no specific reason mentioned for why Dmitri Mendeleev left blank spaces on the periodic table. It is believed that he left these spaces to accommodate elements that were yet to be discovered or to demonstrate the existence of elements with certain properties that were predicted but not yet confirmed. These blank spaces eventually led to the discovery of new elements and validated Mendeleev's periodic table.
How do mendeelevs periodic table and todays periodic table differ?
When Mendeleev's periodic table was devised, some elements hadn't been discovered yet. Therefore, there had to be gaps in it or the table would be rendered incorrect. The rule of similarities states that the elements within a specific period/column are similar in a way and have the same number of electrons in the outer shell. E.g. Period 1 (alkali metals) react strongly with both air and water, have to be stored in oil, and are very alkali, hence the name. Mendeleev used this rule to construct the periodic table. The amazing thing is, he guessed where elements were missing and left gaps. He even estimated their atomic masses! In short, Mendeleev's periodic table had some bits missing. (e.g. technetium, discovered in 1936, a whole 65 years after Mendeleev's table was devised in 1871) P.S. It's Mendeleev, not Mendeelev.
What are the limitations of Mendeleev?
At first, he couldn't find a specific place for hydrogen, and the inner transition elements were not placed correctly.
Why is sodium chloride different in nature from its elements?
It is very normal that different compounds or elements have different properties. Each is a specific entity.
If properties of elements change they are mixed together and the mixture if called what?
If the properties of elements change when they are mixed together, the mixture is called a compound. Compounds result from chemical reactions between elements, where the atoms are bonded together in specific ratios. These compounds often possess unique properties distinct from their individual element components.
How could Dmitri Mendeleev predict the properties of elements that had not yet been discovered?
Dmitri Mendeleev predicted the properties of undiscovered elements by arranging known elements in his periodic table based on their atomic mass and chemical properties. Gaps in the table suggested the existence of unknown elements with specific characteristics based on the trends observed. This systematic approach allowed Mendeleev to make accurate predictions about the properties of elements yet to be discovered.
What is the greatest triumph about mendeleev's periodic table?
Dmitri Mendeleev's greatest triumph with the periodic table was his ability to predict the properties of undiscovered elements. Gaps in the table led him to propose the existence of new elements with specific characteristics, which were later discovered and matched his predictions, confirming the validity of his periodic law.
How did mendeleev make predictions about the properties of elements?
This is a very wordy response, but by setting up the Periodic Table according to elements' properties and characteristics, he was able to predict any given elements' properties because, with the way the Periodic Table is arranged, all of the elements surrounding any specific element would have similar properties to the element that they surrounded. For example, at the time there was no element known as Aluminum, but given the properties of the elements around that area (Group 13), he was able to correctly predict Aluminum's properties. When aluminum was discovered, Mendeleev's predictions were extremely close to the actual element's properties.

How could you use Mendeleevs periodic table to identitify new elements?
Mendeleev's periodic table can be used to predict the properties of unknown elements based on their position in the table in relation to known elements. Gaps in the periodic table can suggest the possibility of unknown elements with specific properties, guiding scientists in their search for new elements that fit those predicted properties. By applying Mendeleev's periodic law, researchers can make educated guesses about the characteristics of undiscovered elements and tailor their experimental efforts accordingly.

Elements can be differentiated by chemical properties .?
Yes, each element has specific chemical properties.
Is a metal that contains other elements to give it specific properties?
A metal that contains other elements to give it specific properties is called an Alloy. Many metals can contain other elements to give the metal specific properties. Steel is an alloy of Iron and carbon. Stainless steels contain various other alloying elements such as Chromium and Nickel.
Elements can be differentiated by their physical properties?
Yes, each element has specific physical properties.
