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.
He arranged the elements in the increasing order of atomic mass and repeating periodic properties.
Dmitri Mendeleev
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.
In Mendeleev's periodic table, a regular and repeating pattern is the arrangement of elements in order of increasing atomic mass, which reveals periodic trends in their chemical and physical properties. Elements with similar properties are grouped together in vertical columns, known as groups or families. For example, elements in Group 1 (alkali metals) exhibit similar reactivity and characteristics. This periodicity reflects the underlying structure of atoms and their electron configurations.
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.
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.
