mendelev's table of evidence is showing that the metals and the elements showing in the Periodic Table is all about the equal amount of protons,electrons,and neutrons showing in the periodic table about the Atomic Mass and number is by the mass equals the protons and neutrons in the nucleus.
example: Helium: symbol:He
atomic number:2
atomic mass muber:4
protons:2
electrons:2
neutrons:2
how do you get 2 for the neutrons???
you subtract 2 from the atomic number and for the mas number you subtract 4
so 4-2=2 and then so the protons and electrons stay the same for the atomic number because protons and electrons they are both equal.

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.
Mendeleevs periodic table of elements was created in 1901?
Actually, Dmitri Mendeleev formulated the periodic law and published his periodic table of elements in 1869. This table arranged elements by increasing atomic mass and grouped them based on similar properties, predicting the properties of missing elements. It was a significant contribution to the field of chemistry.
How did chemist change mendeleevs perioic table in the early 1900s?
Chemists in the early 1900s made changes to Mendeleev's periodic table by rearranging elements based on their atomic number instead of atomic mass, leading to the development of the modern periodic table. This change accurately emphasized the relationship between an element's properties and its atomic number, rather than its atomic mass, and helped to better organize the elements.
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 evidence in small amounts?
Small amounts of evidence are still valuable in supporting a claim or hypothesis. Even a single piece of evidence can contribute to a larger body of knowledge or help in drawing preliminary conclusions. It is important to consider the quality and reliability of the evidence, regardless of the quantity.
Why the improvement in Mendeleevs periodic table was made?
To understand the concept of Periodic Table
What value was there in predicting the properties for gaps in Mendeleevs table?
DiscoVery of new elements
What was the problem with Mendeleevs table?
He left too many spaces between the elements......
What changes were made to the periodic table after Dmitri mendeleevs discovery?
they changed the 3 new Elements.
Mendeleevs periodic table was useful because it enabled scientists to predict properties of unknown?
elements
Was Mendeleevs table a completely regular grid?
not if u mean completely filled in but square by square yes
What is supporting evidence of the whldam resort?
what are supporting evidence of the whyldam resort?
Main idea of mendeleevs first periodic table?
In Mendeleev's periodic table, the elements were arranged in the increasing order of their atomic masses and repeating periodic properties.
What were mendeleevs discoveries and predictions and discoveries abot the periodic table?
Mendeleev predicted that properties of elements are periodic function of atomic mass. He demonstrated it by creating a table.
Which two elements on the periodic tabel would have been placed in different groups in moseleys periodic table but not in mendeleevs?
bi and po
Who is mendeleevs?
Dmitri Mendeleev was a Russian chemist; he proposed the modern Periodic Table of elements in 1869.
Is it legal to charge someone with a felony if there is no evidence supporting it?
No, to be charged for a crime in the court of law there has to be supporting evidence.
