During World War One, in Germany Mendeleev lost both legs and arms but he still had a nose to notice the gases that had blown both his arms and legs off. Due to the gassiness of the air he had to cateogorise the more dangerous gases compared to ones that made you high. He then found a wooden table in the rubble from the explosion of the atomic bomb. He then thought "oh i have an idea, i will put the gases in the table" he then split it in columns and rows with various letters and numbers categorising the gases. It is proven true because many schools over the world now use this in todays learning environment. IT IS LEGENDARY. MENDELEEV FOR KING.

How did Henry Moseley revise mendeleevs periodic table?
In 1914 Henry Moseley found a relationship between an element's X-ray wavelength and its atomic number (Z), and therefore rearranged the table by nuclear charge / atomic number rather than atomic weight. Before this discovery, atomic numbers were just sequential numbers based on an element's atomic weight. Moseley's discovery showed that atomic numbers had an experimentally measurable basis.
Who showed that periodicity depended upon atomic number?
Henry Moseley showed that periodicity depended upon atomic number. He rearranged the periodic table based on atomic number rather than atomic mass, providing a more accurate representation of the periodic trends.
When did mosley create his periodic table?
Henry Moseley created his periodic table in 1913 by arranging elements by their atomic number, a fundamental change from the earlier practice of ordering elements by atomic weight. Moseley's work led to the modern periodic table we use today.
Why did Mendeleev leave a space for the unknown at the time element germanium in his periodic table?
Well, honey, Mendeleev left a space for germanium because he was a smart cookie who knew there was something missing in his periodic table. Turns out, germanium was later discovered and filled that gap, proving Mendeleev's intuition was spot on. So, he left that space like a boss, knowing someone would eventually fill it in.
What contribution did Moseley make to the development of the mondern periodic table?
Mosley arranged elements in order of increasing atomic number

What effect did the discovery of the gallium have on the acceptance of Mendeleev's table?
The close match between Mendeleevs prediction and the actual properties of new elements showed how usefullhis pariodic tabel could be.

What was henry moseley contribution to the periodic table?
In 1912, Henry Moseley, an English physicist showed that periodicity was a fucntion of the atomic number rather than of atomic mass. Our present periodic tables are now constructed using atomic number as the basis of arranging the elements and the periodic law being stated as, the physical and chemical properties of the element are periodic functions of their atomic numbers. This periodic recurrence of properties is emphasized by arranging the elements in a table such that elements with similar properties are aligned in a vertical column. This arrangement is called the Periodic Table.
What contribution did Mosley makers the development of the periodic table?
Henry Moseley showed elements in the periodic table should be in order by their atomic number instead of atomic mass.
Who gave the modern periodic table so?
The modern periodic table was created by Dmitri Mendeleev in 1869. He arranged the elements based on increasing atomic mass and similar chemical properties. Mendeleev's table provided a framework for organizing the known elements and predicting the properties of undiscovered elements.
Who showed that periodicity depended upon atomic number?
Henry Moseley showed that periodicity depended upon atomic number. He rearranged the periodic table based on atomic number rather than atomic mass, providing a more accurate representation of the periodic trends.
How did Henry Moseley affect the development of the periodic table?
He discovered that each element has its own atomic number.In 1914 Henry Moseley found a relationship between an element's X-ray wavelength and its atomic number (Z), and therefore resequenced the table by nuclear charge rather than atomic weight. Before this discovery, atomic numbers were just sequential numbers based on an element's atomic weight. Moseley's discovery showed that atomic numbers had an experimentally measurable basis.

Is californium a solid liquid or gas at room temp?
You know that little chart they showed you in class? The one with all the boxes with letters and numbers in them? What's it called, the periodic something or other? Yeah, use that.
What discovery did Henry Moseley lead him to reorganize the periodic table?
In 1914 Henry Moseley found a relationship between an element's X-ray wavelength and its atomic number (Z), and therefore resequenced the table by nuclear charge rather than atomic weight. Before this discovery, atomic numbers were just sequential numbers based on an element's atomic weight. Moseley's discovery showed that atomic numbers had an experimentally measurable basis.
What did Henry Moseley change about the periodic table?
Henry Moseley reorganized the periodic table based on atomic number instead of atomic mass, thereby providing a more accurate and clear arrangement of elements. This reorganization helped to explain the discrepancies and predict properties of certain elements that were not well-understood before.
