Do the relative positions of there elements in the periodic table with the prediction made in the introduction about their strut re?
The relative positions of elements in the Periodic Table correlate with their predicted structures based on periodic trends such as atomic size, electronegativity, and valence electron configuration. Elements in the same group typically exhibit similar bonding characteristics and structural properties due to having the same number of valence electrons. For instance, metals tend to form crystalline structures, while nonmetals may exhibit molecular or network structures. Thus, the predictions made about their structures align with their positions in the periodic table.

Who drew the first periodic table?
Dmitri Mendeleev is credited with creating the first periodic table of elements in 1869. He organized the elements based on their properties and atomic weights, allowing for the prediction of undiscovered elements.
What does the periodic law establishes?
The periodic law establishes that elements are arranged in order of increasing atomic number in the periodic table, and elements with similar properties are grouped together in columns called groups. This law allows for the prediction of an element's properties based on its position in the periodic table.
Which answer best explains how the modern periodic table was derived?
The modern periodic table was derived based on the periodic law, which states that the properties of elements are a periodic function of their atomic number. Dmitri Mendeleev and Lothar Meyer independently developed versions of the periodic table by arranging elements in order of increasing atomic number and grouping elements with similar properties together. Mendeleev's table also left gaps for undiscovered elements, allowing for the prediction of properties of these elements.
Who is Dimetri Mendeleeve?
Dimetri Mendeleev was a Russian chemist. He is credited for his version of periodic table which was better than anyone else's during that time. He organized elements almost accurately and formed the basis for the Modern Periodic Table.
Why is the mendeleevs table called the periodic table?
Because the properties of the elements change in a periodic fashion. In the early versions, when fewer elements were known, the chemically similar elements were thought to occur every eight positions.
Do the relative positions of sucrose in the periodic table agree with the theoretical prediction about the kind of compound these elements should form?
Yes, the relative positions of carbon, hydrogen, and oxygen in the periodic table agree with the theoretical prediction about the kind of compound they should form. Carbon and oxygen are in the same group and tend to form covalent compounds, while hydrogen typically forms compounds with other elements through ionic or covalent bonds. Sucrose, a compound made of carbon, hydrogen, and oxygen, is a covalent compound in line with these predictions.
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.
Who drew the first periodic table?
Dmitri Mendeleev is credited with creating the first periodic table of elements in 1869. He organized the elements based on their properties and atomic weights, allowing for the prediction of undiscovered elements.
What prediction did Mendeleev make that came true in less than 20 years later?
Mendeleev's prediction that there were elements missing from the periodic table was confirmed when gallium was discovered in 1875 and germanium in 1886, fulfilling the gaps Mendeleev had left in his periodic table.
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.
When was the periodic table created and who by?
The periodic table was created by Dmitri Mendeleev in 1869. He organized the elements based on their chemical properties and their atomic weights, creating a system that arranged the elements into groups and periods. This arrangement allowed for the prediction of missing elements and became the basis for the modern periodic table.
What trends were seen in Mendeleev's periodic table?
he arranged his Periodic Table by each elements Atomic Mass
What does the periodic law establishes?
The periodic law establishes that elements are arranged in order of increasing atomic number in the periodic table, and elements with similar properties are grouped together in columns called groups. This law allows for the prediction of an element's properties based on its position in the periodic table.
Why did Mendeleev create the periodic table?
Dmitri Mendeleev created the periodic table to organize and classify the elements based on their properties and atomic weights, allowing for easier understanding and prediction of element behavior.
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.
How are the elements in the first periodic table arranged?
In the first Periodic Table by Mendeleev, he arranged the elements in the increasing order of their atomic masses and repeating properties.
What properties of these elements are indicated by their positions in the periodic table?
For example metal or nonmetal character, radioactivty, atomic weight, reactivity.
