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.
What else can I help you with?
Why did mendeleev not include germanium in the periodic table?
He could not because it had not yet been discovered when he created the table. However he was able to determine that an element was missing at that location and predict the properties it would have when it was discovered. When germanium was discovered and named, his predictions were found to be very accurate.
Could be predicted using Dmitri Mendeleev's periodic table?
Dmitri Mendeleev's periodic table allowed for the prediction of undiscovered elements based on the patterns of known elements. He arranged elements by increasing atomic mass and grouped them by similar chemical properties, which led him to leave gaps for elements he anticipated would be found later. For instance, he predicted the existence of gallium and germanium before they were discovered, as their properties aligned with the trends of elements in their respective groups. His periodic table's structure demonstrated that elements exhibit periodicity, enabling accurate predictions about their characteristics.
Is it accurate to say thet helium has no properties?
Well it is partly true. Helium has physical properties like density, boiling point, conductivity etc. But it has no chemical property.
What is an accurate comparison of the properties of compounds and the properties of the elements that the compounds contain?
Compounds have unique properties distinct from their constituent elements, as they exhibit new chemical and physical characteristics through chemical bonding. The properties of compounds are determined by their molecular structure and interactions between atoms. In contrast, the properties of elements are based on their atomic structure and individual chemical behavior.
Why was newlands law of octavaces rejected?
Newlands' Law of Octaves was rejected primarily because it was based on the observation of only 56 elements, which limited its applicability. While it successfully grouped elements with similar properties in the first few rows, it failed to accommodate new elements discovered later and did not apply well to heavier elements. Additionally, the law suggested that elements' properties repeat every eight elements, which was not universally accurate. This led to the development of the periodic table as a more comprehensive framework for organizing elements based on atomic number and properties.
How could Mendeleevs table be used to predict the properties of elements that had not been discovered?
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.
How was Menndeleyev able to predict the existence of elements that had not yet been discovered?
Mendeleev left gaps for undiscovered elements. He predicted their properties which were found to be accurate later.
Mendeleev's periodic table was accurate enough that he was able to use it to predict the existence and several properties of certain elements that had not yet been discovered true or false?
True.
When was tesselations discovered?
In 1619 tessellations was studied and discovered and in 1891 it was proven to be correct and accurate.
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 argument for the existence of global warming?
Thermometers and accurate measurements and data keeping prove that the earth is warming.
How many actors are there in Hollywood?
743 and a half :) 743 and a half :)
What effect did th discovery of gallium have on the accepteance of mendeleevs table?
Mendeleev had some empty spaces in his table. On being asked why he left spaces, instead of seeing it as a drawback, he confidently said that those were the places for "yet to be discovered elements". He named them by prefixing the Sanskrit numeral "Eka-" to the preceding element.For example, he named Gallium as "Eka-aluminium", Germanium as "Eka-Silicon" and so on. Later, when a new element was found and was named as Gallium, it was observed that it had almost same properties as that of Eka-Aluminium predicted by Mendeleev. As his predictions were almost accurate, other scientists began to accept that his classification was indeed better than any others'. And so, it was accepted.
Why dobereiners triad was rejected?
Döbereiner's triads were rejected because they did not work for all elements and their properties as more elements were discovered. They were limited to grouping only a few elements with similar properties, and the periodic table provided a more comprehensive and accurate organization of elements based on atomic number and properties.
What properties are the most accurate to use when describing an object?
Shape, dimensions, mass, colour.
