What else can I help you with?
The periodic table is arranged according to repeated changes in properties of elements?
number of electrons
Why are periodic tables called that?
Because the elements that have similar properties are arranged in groups - or 'periods'.
The periodic law states that the properties of elements will repeat when the elements are arranged by _______.?
If the elements are arranged in the order of their increasing atomic numbers, there properties are repeated in a periodic manner.
What did Mendeleev conclude when constructing the periodic table?
Dmitri Mendeleev concluded that when elements are arranged in order of increasing atomic mass, their properties repeat periodically. He left gaps for undiscovered elements and predicted the properties of these missing elements based on their neighboring elements. This led to the development of the modern periodic table.
Why did Mendeleev called his arrangement of elements the periodic table?
If the elements (which were discovered by his time) were organized in the increasing order of their atomic weight, they will exhibit an apparent periodicity of properties. It also had the ability to predict physical and chemical properties of some undiscovered elements.
Mendeleev's pattern repeated after how many elements?
The properties were repeated after 8 elements.
Why the scientist who made the first periodic table didn't understand why properties of elements repeated?
Dmitri Mendeleev, who created the first periodic table, did not understand why the properties of elements repeated because he did not know about atomic structure and the concept of atomic number. It was later discovered that the repetition of properties was a result of the elements being arranged in order of increasing atomic number, leading to the modern periodic table.
What determined the order of elements across a row in Mendeleev's periodic table?
Mendeleev organized the elements in his periodic table based on increasing atomic mass. He noticed that certain properties repeated periodically when the elements were arranged in this way.
What information did Mendeleev use to try to find a pattern in elements?
Mendeleev arranged elements based on their atomic weights and chemical properties. He noticed that when he arranged elements in order of increasing atomic weight, certain properties repeated at regular intervals, leading to the development of the periodic table.
What pattern did Mendeleev arrange elements in?
Dmitri Mendeleev arranged the elements in his periodic table in order of increasing atomic mass and grouped elements with similar properties together. This arrangement helped him to identify periodic trends and predict the properties of undiscovered elements.
What did Meyer's do with the periodic table?
He had arranged the order of the elements due to their atomic weights they fall into groups in which similar chemical and physical properties are repeated at periodic intervalsThis Answer Is From @I'mSomthing_Nice on Twitter , FOLLOW ME , I FOLLOW BACK ( :
What did the scientist Dmitri mendeleev classify in a chart called the periodic table?
he arranged the various in the increasing order of atomic mass and found that some properties of the elements were repeated at certain intervals of atomic masses
