Why was Mendeleev's periodic table considered a good model?
Mendeleev's periodic table was considered a good model because it organized elements based on their atomic mass and properties, allowing for predictions of undiscovered elements and their properties.
Why are there no famous women scientists associated with cell theory?
There are no women scientists associated with cell theory because the boys are being sexist.
Where are The strongest halogens located in the periodic table?
The Halogen group is under Period 7 of the periodic table of elements, right next to the noble gasses. Because electronegativity is directly related to reactivity and stability of bonding, the strongest halogens would be near the top of the halogens. This is because electronegativity increases as you go up a column in the periodic table. So fluorine and chlorine would be the "strongest" of the halogens.
Why did Rosalind Franklin not receive a Nobel Prize like other scientists?
because she is already dead when the nobel prized
How did mendelevium the element get its name?
The name of the chemical element mendelevium is derived from the name of the Russian chemist Dimitri Ivanovici Mendeleev, the discoverer of the periodic table of elements.
Why did scientists try to improve Mendeleevs table?
Scientists tried to improve Mendeleev's periodic table to account for the discovery of new elements, better organize elements based on their properties, and to address inconsistencies in the original table. This led to the development of the modern periodic table with elements arranged in increasing atomic number and grouped based on similarities in chemical properties.
What is the significance of the periodic table in understanding the groupings and properties of elements?
The periodic table is significant because it organizes elements based on their properties and groupings. This organization helps scientists understand the relationships between elements and predict their behaviors.
Why is mendeleevs periodic table a model?
Mendeleev's periodic table is considered a model because it organizes elements based on their atomic mass and chemical properties, highlighting periodic trends and relationships among them. This arrangement allowed Mendeleev to predict the existence and properties of undiscovered elements, demonstrating the table's utility in understanding elemental behavior. Additionally, the structure of the table reflects the periodic law, which states that the properties of elements are a periodic function of their atomic mass. Thus, it serves as a foundational framework for modern chemistry, despite later modifications based on atomic number.
What have predictable chemical properties?
Elements in the periodic table have predictable chemical properties based on their position because they have the same number of valence electrons. This determines how they will react with other elements and molecules. The periodic table's structure helps scientists predict the behavior of elements based on their properties.
Mendeleev's periodic table was use ful because it enabled scientists to predict properties of unknown?
elements and corrected discrepancies in existing elements. Mendeleev's periodic table also allowed for the organization of elements based on their atomic mass and chemical properties, which laid the foundation for the modern periodic table.
The periodic table is called periodic because the?
in 1869 periodic trends in the properties of the then-known elements
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.
What is periodic about the periodic table?
The periodic table is called "periodic" because it arranges elements in rows called periods based on their atomic number and chemical properties, showing a repeating pattern of properties.
What is the significance of the periodic table in understanding the properties and formation of diamond?
The periodic table is important in understanding diamond properties and formation because it shows the arrangement of elements based on their atomic structure. Diamonds are made of carbon atoms arranged in a specific crystal structure, which is influenced by the properties of carbon as an element. By studying the periodic table, scientists can predict how carbon atoms will interact and form the unique structure of a diamond.
Why were other scientists skeptical about mendeleev?
Other scientists were skeptical about Mendeleev's periodic table because it contained gaps for elements that had not yet been discovered and because it did not follow strict atomic weights as a basis for organization. Additionally, there was skepticism about his prediction of the properties of undiscovered elements.
Why scientists believe no elements are missing in the periodic table?
The periodic table contains all the known elements. Scientists have spent decades looking for new elements and, so far, haven't found any beyond what are on the periodic table as it stands now.
What is the Significance of the periodic table of elements?
The periodic table of elements is significant because it organizes all known elements based on their atomic number, electron configuration, and chemical properties. It allows scientists to predict the behavior and properties of elements and to discover new elements. The periodic table is a fundamental tool in chemistry and serves as the basis for understanding the structure and interactions of matter.
