Atomic number or number of protons.
The Modern Periodic Law states that there will be a periodic repetition of properties when the elements are arranged according to increasing atomic number.
Now modern periodic table is arranged in order of increasing atomic number. The properties are found to be periodic when arranged in this pattern.
number
Mendeleev arranged the elements in a table in the increasing order of atomic masses and repeating periodic properties. In the modern long-form of periodic table, the elements are arranged in the increasing order of atomic number and repeating periodic properties.
The elements arranged according to their atomic number in the table are called periodic table.
The Modern Periodic Law states that there will be a periodic repetition of properties when the elements are arranged according to increasing atomic number.
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.
Mendeleev arranged the elements in his periodic table in order of increasing atomic mass while also grouping elements with similar properties together. His periodic table laid the foundation for the modern periodic table we use today.
Now modern periodic table is arranged in order of increasing atomic number. The properties are found to be periodic when arranged in this pattern.
number
Dmitri Mendeleev and Lothar Meyer first arranged the elements in the increasing order of atomic masses. Bohr and Henry Moseley then arranged the elements in the increasing order of atomic number.
Moseley arranged the elements according to increasing atomic number.
Mendeleev arranged the elements in a table in the increasing order of atomic masses and repeating periodic properties. In the modern long-form of periodic table, the elements are arranged in the increasing order of atomic number and repeating periodic properties.
If the elements are arranged in the order of their increasing atomic numbers, there properties are repeated in a periodic manner.
The elements arranged according to their atomic number in the table are called periodic table.
In the modern periodic table, the elements are arranged in the increasing order of their atomic number and repeating properties.
Periodic table contains elements arranged in rows and columns. It is done according to increasing atomic number.
