Increasing Atomic Mass
Increasing atomic mass
He arranged the elements in the increasing order of their atomic masses and repeating periodic properties.
He arranged the elements in the increasing order of atomic mass and repeating properties so that it is easy to study the properties / reactivities of the elements.
Dmitri Mendeleev
He arranged the elements in the increasing order of atomic mass and repeating periodic properties.
In the first Periodic Table by Mendeleev, he arranged the elements in the increasing order of their atomic masses and repeating properties.
In Mendeleev's periodic table the elements are arranged in increasing atomic mass and repeating properties whereas in in the modern periodic table the elements are arranged in increasing atomic number and repeating properties.
Dmitri Mendeleev's arrangement of elements is called the periodic table. He organized the elements based on their atomic mass and chemical properties, leading to the development of the modern periodic table used today.
Chemical elements arrangement was the object of study for Mendeleev.
Dmitri Mendeleev arranged the elements in his periodic table by increasing atomic mass because he noticed a periodic pattern in properties repeating every 8th element. This arrangement allowed him to predict the properties of undiscovered elements and left gaps for them in his table.
Increasing Atomic Mass
Mendleef arranged the elements in the increasing order of their atomic masses due to which elements having same properties were placed in the same group and there were few exceptions.
