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.
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 do you mean by group in periodic table?
The columns in the periodic table are groups, also called families because the elements in a group have similar properties.
Why did mendeleev leave gaps in the table?
Scientists suggest Mendeleev left gaps in the periodic table because Mendeleev knew the elements existed; however, was unable to prove it.
What is the periodic law?
Periodic Table of elements.
Mendeleevs periodic table was useful because it enabled scientists to predict properties of unknown?
elements
Why did scientists try to improve Mendeleevs table?
because they did not feel that his table was well enough to be used world wide.
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.
Why are periodic tables called that?
Because the elements that have similar properties are arranged in groups - or 'periods'.
What did Mendeleevs periodic table look like?
It looks the same as it did when Mendeleev created it. There are no changes made to the table throughout the years because Mendeleev had predicted the correct placement for all of our current known elements.
What is The periodization?
The periodic law is:When elements on the periodic table are arranged by atomic number, relationships and similarities in properties can be seen.This means that the properties of the elements are periodic, or recurring, functions of their atomic numbers. Because of this phenomenon, it is possible to construct a table that graphically reflects the relationship between the properties and atomic number. This table is called the Periodic Table.
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.
The periodic table is called periodic because the of the elements repeat periodically?
The periodic table is layed out to show "Periodic" chemical properties such as the number of protons in the nucleus of the elemnt, and the number of valence electons it has.
Why are lanthandies placed below the periodic table?
Lanthanides and actinides are placed below the periodic table because of their unique physical and chemical properties.
What do you mean by group in periodic table?
The columns in the periodic table are groups, also called families because the elements in a group have similar properties.
Why was the periodic table created?
It wasn't necessary, but it was very helpful. By arranging the elements in a periodic table, it makes it much easier to see patterns and trends in the properties of the elements. For instance, all of the elements in each column of the periodic table have similar properties because their electron configurations are related. Using the periodic table, you can predict with fairly good accuracy the properties of an element you've never even seen just based on where it is in the periodic table. It is a very powerful tool for chemists.
