Mendeleev positioned the elements primarily based on their Atomic Mass and their chemical properties. He arranged them in a Periodic Table format, grouping elements with similar properties into columns, which allowed him to predict the existence and properties of undiscovered elements. This arrangement highlighted the periodic trends in element behavior, demonstrating that properties recur at regular intervals when elements are ordered by increasing atomic mass.
What else can I help you with?
How are the properties displayed in the periodic table?
Elements with same property are grouped together. Property can be estimated by its position.
Who arranged the elements by atomic mass and used it to predict properties of missing elements?
Independently by Dmitri Mendeleev and Lothar Meyer in 1869
According to the increasing of what did Medeleev arrange the known chemical elements in a table?
Dmitri Mendeleev arranged the known chemical elements in a table according to their increasing atomic mass.
Why did Medeleev arrange he order of elemts of mass?
Dmitri Mendeleev arranged the elements in his periodic table by increasing atomic mass because he noticed a periodic pattern in properties repeating every 8th element. This arrangement allowed him to predict the properties of undiscovered elements and left gaps for them in his table.
What is the property of an element that does not depend on the amount of elements is called?
intensive property
Who created the first version of the modern periodic table of elements and used it to predict undiscovered elements?
Dmitri Mendeleev
How are the properties displayed in the periodic table?
Elements with same property are grouped together. Property can be estimated by its position.
How did dimitri medeleev organize the periodic table?
Dmitri arranged elements in rows and columns. According to him, the properties of elements are periodic functions of their atomic weights.
Who arranged the elements by atomic mass and used it to predict properties of missing elements?
Independently by Dmitri Mendeleev and Lothar Meyer in 1869
What is medeleev's prediction?
It's probably Mendeleev you're after. He came up with the first version of a Periodic Table of the elements, and used this to predict the properties of elements that hadn't been discovered at that time.
According to the increasing of what did Medeleev arrange the known chemical elements in a table?
Dmitri Mendeleev arranged the known chemical elements in a table according to their increasing atomic mass.
What atomic property determines an elements position on the periodic table?
the number of protons in the nucleus and the number of electrons in the valence orbital
What scientist before medeleev developed the first ideas arranging the elements?
Before Mendeleev, Dobereiner, De-chancourtis, Newland and Lother Meyers had already given their respective periodic arrangement of elements, but none of the models were accepted as they had many limitations...
Elements have their position on the periodic table because?
atomic no. or basically according to the no. of electrons in their outermost shell whcih reflect the property of individual atom
How did medeleev organize the periodic table?
he based it on his favourite game
Is a size property of elements?
No
Why did Medeleev arrange he order of elemts of mass?
Dmitri Mendeleev arranged the elements in his periodic table by increasing atomic mass because he noticed a periodic pattern in properties repeating every 8th element. This arrangement allowed him to predict the properties of undiscovered elements and left gaps for them in his table.
