Moseley's periodic table?
Moseley's periodic table was developed by English physicist Henry Moseley in 1913. He rearranged the elements on the periodic table based on their atomic number rather than atomic mass, which led to the modern form of the periodic table. Moseley's work provided a clearer understanding of the organization of elements and their properties.
In 1913 who updated the periodic table by changing how the elements are arranged?
Henry Moseley updated the periodic table in 1913 by arranging elements by atomic number instead of atomic mass. His work reorganized the elements and corrected inconsistencies in the periodic table.
In Dmitri mendeleev's periodic table elements were placed in order of?
In Dmitri Mendeleev's periodic table, elements were arranged in order of increasing atomic mass. Mendeleev noticed that when elements were organized this way, they exhibited periodic trends in their chemical properties. This arrangement allowed him to predict the existence and properties of undiscovered elements by leaving gaps in the table. His work laid the foundation for the modern periodic table, which is now organized by atomic number instead.
Meyer contributions to the periodic table are?
Mendeleev developed the periodic table of elements by arranging the elements in order of increasing atomic mass in 1869. He discovered that elements with similar properties occurred in a periodic pattern. He was able to predict the properties of elements that were missing at the time because of this pattern. In 1914, Moseley contributed to the periodic table by reorganizing the elements according to atomic number.
Who constructed the periodic table of elements?
Dmitri Mendeleev constructed the periodic table of elements in 1869 based on atomic mass( which is how much an atom weighs). this however was changed many many years later resulting in our current design of the periodic table which is based on atomic number instead.( the number of protons in an atom.)

How do you you work out the number of neutrons in an atom?
Atomic Mass minus atomic number
What is the important work of dmitr mendeleev?
he invented an early version of the periodic table, and was able to use it to predict what unfound elements properties would be he follow the periodic law and place the similar elements according their mass number.

Who is the scientisit is credited with the creation of the periodic table?
Dmitri Mendeleev is credited with the creation of the periodic table. He arranged the elements based on their atomic mass and chemical properties, and left gaps for undiscovered elements. His work laid the foundation for our modern understanding of the periodic table.
What was Mendeleevs proposal?
Dmitri Mendeleev was a Russian chemist who proposed the Periodic Law. He published the first periodic table of the chemical elements in 1869, based on the increasing atomic masses of the different elements.
Who constructed the periodic table of elements?
Dmitri Mendeleev constructed the periodic table of elements in 1869 based on atomic mass( which is how much an atom weighs). this however was changed many many years later resulting in our current design of the periodic table which is based on atomic number instead.( the number of protons in an atom.)
How do you use the symbol of an element to work out the number of protons neutrons and electrons in an atom?
The number of protons in an atom is equal to the atomic number, which corresponds to the position of the element in the periodic table. To find the number of neutrons, you subtract the atomic number from the atomic mass. The number of electrons is typically equal to the number of protons in a neutral atom.
What is period lease?
the Periodic Table is something lame you use to work with science.
When did Meyer contribute the periodic table?
Meyer developed a table that was similar to modern periodic table. But his work was published later after Mendeleev.
What did mendeleev discover?
Dmitri Mendeleev discovered the periodic law and created the periodic table of elements. He arranged elements by atomic mass and properties, leaving gaps for undiscovered elements which he later predicted and found to exist. This work laid the foundation for modern chemistry.
