no they are not.they are arranged in periods
Moseley arranged elements according to atomic number.Mendeleev arranged elements according to atomic mass.
Elements arranged in one column exhibit similar chemical properties. Elements in same column also have similar physical properties. Also elements in same column has similar electronic configuration.
No. When the elements are arranged in order of increasing atomic number there is a periodic repetition of their physical and chemical properties.
The answer to, ' when repeating chemical and physical properties of elements change periodically with the elements' atomic numbers it is called the?'Periodic law, is the answer. PERIODIC LAW !orPeriodicity of the chemical elements properties.
elements in the same group
"When elements are arranged in order of increasing atomic number, there is a periodic repetition of their chemical and physical properties" is a statement of the periodic law.
Moseley arranged elements according to atomic number.Mendeleev arranged elements according to atomic mass.
Dmitri Mendeleev
Periodic Law
He arranged the elements in the increasing order of their atomic masses and repeating periodic properties.
The physical and chemical properties of the elements are periodic functions of their atomic numbers.The periodic law states that the physical and chemical properties of elements are periodic functions of their atomic numbers. They influence the characters of an element more than atomic weight.
Elements arranged in one column exhibit similar chemical properties. Elements in same column also have similar physical properties. Also elements in same column has similar electronic configuration.
These elements have similar chemical and physical properties.
Madeleev originally arranged the elements in the first periodic table by their average atomic masses. Later it was changed to atomic number by Moseley, or the number of protons each of that element's atom has.
The different elements are arranged in the increasing order of their atomic number and repeating chemical / physical properties.
Mendeleev's table was also based upon his Periodic Law, which stated that when elements are arranged by increasing atomic number, there is a periodic repetition of similar chemical and physical properties.
Because this arrangement of chemical elements is rational, satisfy the need of classification in chemistry and is very important for the study of chemical and physical properties of chemical elements, including the new discovered or prepared elements.
