one is beryllium, others i don't know.
Atomic Masses
Mendeleev listed the atomic weights and chemical properties of elements as he began to organize them. He noticed that elements with similar properties appeared at regular intervals when arranged by increasing atomic weight.
Mendeleev arranged elements in his periodic table on the basis of increasing atomic masses.
By the increasing Atomic Mass.
Dimitri Mendeleev arranged the known chemical elements into a systematic chart known as the Periodic Table. By organizing the elements by atomic number and properties, this table allows for predictions of the behavior and characteristics of elements within each group.
Atomic Masses
Mendeleev listed the atomic weights and chemical properties of elements as he began to organize them. He noticed that elements with similar properties appeared at regular intervals when arranged by increasing atomic weight.
Dmitri mendeleev arranged elements in order of increasing atomic masses. He considered chemical properties of the elements, their oxides and nitrides.
Dmitri Mendeleev arranged elements in order of increasing atomic masses. He placed elements in rows and columns.
He arranged the elements in the increasing order of their atomic masses and repeating periodic properties.
Mendeleev arranged elements in his periodic table on the basis of increasing atomic masses.
Mendeleev arranged the elements are arranged in order of increasing atomic masses. He founded that properties of elements are periodic when arranged in this pattern.
Dmitri Mendeleev was a scientist. He arranged elements in order of increasing atomic masses.
By the increasing Atomic Mass.
Dmitri Ivanovich Mendeleev
Mendeleev organized the elements according to their increasing atomic masses and considered their fundamental properties . He also considered the Hydrides and Oxides formed by the elements.
When Mendeleev developed his periodic table, he placed the greatest emphasis on organizing the elements based on their atomic masses and grouping elements with similar properties together. He also left gaps for undiscovered elements and predicted their properties.
