How did Moseley arrange the periodic table?
How did Moseley arrange the periodic table?
Answer and Explanation: The answer is (a) by atomic number. Henry Moseley arranged the elements in the periodic table by their atomic number, or the number of protons.
When was Moseley’s periodic table arranged?
In 1913 Henry Moseley decided to organized the periodic table by atomic number. This solved the atomic mass issues.
How did Mendeleev and Moseley arrange the periodic table?
The Mendeleev periodic table has chemical elements arranged based on their atomic masses. The Moseley periodic table has chemical elements arranged based on their atomic numbers.
How Moseley arranged elements by their atomic numbers?
Henry Moseley solved these inconsistencies by determining that the properties of elements were a function of their atomic numbers, i.e., the number of protons in the nucleus of the atom. Since this discovery, elements in the periodic table are arranged in order of increasing atomic number.
How is Moseley’s basis for arranging the elements different from Mendeleev’s?
How is Moseley’s basis for arranging the elements different from Mendeleev’s? He arranged them by atomic number instead of by atomic mass. This fixed the discrepancies with elements such as tellurium and iodine.
What is the difference between Mendeleev’s and Moseley’s periodic table?
Therefore, the main difference between Mendeleev’s and Moseley’s arrangements of elements in the periodic table is that Mendeleev arranged elements ascendingly according to atomic masses, while Moseley arranged them ascendingly according to atomic numbers.
What was the difference between Mendeleev’s and Moseley’s periodic tables?
How was Mendeleev’s periodic table arranged?
Mendeleev arranged the elements in order of increasing weight and broke them into rows such that elements in each column shared valence, the number of other atoms they combined with, as well as other properties.
Who first arranged the periodic table?
Dmitri MendeleevPeriodic table / Inventor
How was Moseley’s organizing principle more effective than Mendeleev’s arrangement?
Mendeleev and Meyer proposed periodic tables showing a relationship between atomic mass and elemental properties. Moseley organized the elements by atomic number instead of atomic mass.
What are some similarities between Mendeleev’s and Moseley’s periodic tables?
Similarities between Mendeleev’s periodic and Modern periodic table:
- Elements are arranged in groups and periods.
- Elements with similar properties are placed in the same group.
- Metals and non-metals are placed separately.
