How did Moseley solve the problem of elements that did not fit the pattern according to their properties?
He rearranged the table, placing elements in order of atomic weight, not by property. This resulted in elements that had similar properties but were actually very unrelated from being placed incorrectly, and lead to them being put where it made more sense. After the reordering, they were also very much aligned by their properties, thus fixing the problem of those elements that didn't fit.
What else can I help you with?
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.
What scientist determined that atomic mass did not determine the pattern of the periodic table?
Dmitri Mendeleev, a Russian chemist, determined that atomic mass alone did not determine the pattern of the periodic table. He organized the elements based on their properties and predicted the existence of undiscovered elements based on the periodic trends he observed.
Is it true or false that across a period from left to right the properties of elements change according to a pattern?
Yes, properties change according to pattern along a period. For example- atomic size decreases along a period. This is due to increasing nuclear charge.Yes, most of the properties change according to a pattern. Atomic radii, electronegativity changes according to a pattern. But properties like ionization energy does not change according to a pattern.
What pattern did Mendeleev find while organizing information on the elements Answer NOW?
Mendeleev was the scientist who first devised the periodic table of the elements. The pattern he found was that elements have periodic, or repeating series of properties. If you write down the elements in a series according to increasing atomic number, there is a repeating pattern; first metals, then nonmetals, then noble gases, then back to metals. This pattern helps us to understand why elements have the particular chemical properties that they have. It is fundamental to the science of chemistry.
What elements properties follow a pattern that repeats every?
The properties of elements that follow a pattern that repeats every eight elements are known as the periodic properties. These properties include atomic radius, ionization energy, electron affinity, and electronegativity, which exhibit periodic trends across periods (rows) in the periodic table.

Properties of elements change according to a pattern across the?
Groups of the Periodic Table of Elements.
What is the repeating pattern of elements of their properties called?
The repeating pattern of elements and their properties in the periodic table is called periodicity. This refers to the predictable trends in properties such as atomic size, ionization energy, and electronegativity as you move across a period or down a group in the table.

How did mendeleev organize the elements to create a periodic table?
Mendeleev organized the elements by increasing atomic mass and grouping elements with similar properties into columns called groups. He left gaps in the table for undiscovered elements and predicted properties of these elements based on the periodic pattern of known elements.

What did scientist discover when they arranged elements in order of increasing atomic mass?
they discovers a repeating pattern of properties
How was Dmitri Mendeleev able to predict the properties of germanium?
Dmitri Mendeleev was able to predict the properties of germanium by leaving gaps in his periodic table for elements that were yet to be discovered. He noticed a pattern in the properties of known elements and used this pattern to predict the existence and properties of undiscovered elements, such as germanium.
Who arranged the elements in the periodic table according to increasing weight?
Dmitri Mendeleev is credited with arranging the elements in the periodic table according to increasing weight. He also left gaps for undiscovered elements and predicted their properties, leading to the development of the modern periodic table.
What pattern Mendeleev discover when he arranges the elements?
A Pattern of properties appeared when he arranged the elements in order of increasing Atomic Mass
