He didn't just arrange the elements based on Atomic Mass. If the chemical properties weren't similar - he'd change the order of them. He left gaps for elements that he knew would later be discovered and was successful in predicting the chemical properties of Ga and Sc which were later discovered.

Which of mendeleev table show the elements following a pattern that repeats every seven elements?
It is The Periodic Table of Elements
How did errors in the Mendeleev periodic table begin to show up?
When it was discovered that Mendeleev's table was based on the wrong characteristic. He believed that it was the mass of the elements that affected their properties. It is, in fact, their atomic numbers
Who invernted the periodic table?
In 1869, a Russian chemist named Dmitri Mendeleev invented this table to help show trends in the behavior of chemicals.
How modern periodic law removed the defects of mendeleevs system of classification?
The properties of elements are the periodic function of their atomic numbers. REMOVAL OF DEFECTS OF MENDELEEV'S PERIODIC TABLE periodic table obtained on the basis of increasing atomic numbers has removed defects of Mendeleev's periodic table . 1) POSITION OF ISOTOPES : since the isotopes of the same elements have the same atomic number, they are given the same place in the table. 2) POSITION OF RARE EARTHS: These elements are separately placed at the bottom of table . similarly Acton elements ( which were discovered after Mendeleev ) are also placed at the bottom of the periodic table. 3) ANOMALOUS PAIRS. the arrangement according to the atomic number show that their placements are correct.
What was Dmitri Mendeleev able to do show the value of his contribution?
he created the first periodic table tat organized elements by their atomic number.
What contribution did Dmitri Mendeleev make in chemistry what was he able to do to show the valeu of his contribution?
He created the first perodic table and organized the element in the periodic table by atomic mass
Who is the founder of the periodic table?
The Russian Chemist, Dmitri Ivanovich Mendeleyev, founded the periodic table. Mendeleyev was the first person to show the similarities and trends in the properties of chemical elements, and he was acknowledged 50 years later when the 101st element was named after him, mendelevium.

How would you find the grams on the periodic table?
The periodic table doesn't show grams; and which grams ?
What is listed in the periodic table?
The periodic table is a list of the chemical elements. They are arranged to show chemical relationships.
What does the periodic table show us about atoms of various elements?
Periodic table show that elements have properties which are periodic in nature. These properties can be grouped together.
Can you show me the periodic table?
By there properties: Metals, Non-Metals and Metalliods.
