Why is gold Au on the periodic table
The golden symbol on the rare table is Au, favored for its Latin theme Aurum. It is an expensive metal with a high boiling point, commonly used as valuable currency and/or jewelry.
What is gold made from
Gold is now a chemical element with 79 protons in each nucleus. Any atom containing 79 protons is a large atom, and all gold atoms behave chemically in the same way. So, in principle, we can get gold by easily collecting 79 protons (and a lot of neutrons to make the nucleus stable).
Is gold an element or atom
Gold is a chemical process with the symbol Au and 79 atomic information. Classified as a transitional stainless steel, gold is a solid in atmospheric space.
Why is modern periodic table better than Mendeleev’s periodic table
The periodic table of Mendeleev largely depends on the relationship between climatic properties and the atomic mass of the element’s body. But a modern review sees atomic number as a fundamental property defining properties with elements. The modern periodic table is best suited to the shortcomings of the periodic table of holidays.
Why Mendeleev had to reverse the order of some of the elements in his periodic table and describe the effect this had on the modern periodic table
Explain why Mendeleev fixed the order of some of the elements in his periodic table and describe the impact this had previously on the modern periodic table. He arranged the table according to the volume of the atom. It was later discovered that real atoms are arranged according to the number of protons in each nucleus.

What is the difference between Mendeleev’s periodic table and modern periodic table give at least 3 differences
Elements are classified according to the best order of their atomic numbers. Isotopes stay in the same place due to the same atomic number. Note: Silver, copper and gold minted metals are listed in the Periodic Table of Mendeleev. …These shortcomings are corrected by the fashionable Periodic Table.
How were the positions of cobalt and nickel resolved in the modern periodic table How were the positions of isotopes of various elements decided in the modern periodic table is it possible to have an element with atomic number 1.5 placed between hydrogen
Answer: The modern periodic table is based on the atomic number of the elements, and the elements are always listed in ascending order of their atomic number. Cobalt has an atomic number of 27 and Penny has an atomic number of 28. Therefore, these elements are arranged with respect to their correct order of increasing angles.
How did Mendeleev assemble the elements in periodic table and how many elements were in the Mendeleev periodic table
In 1869, Dmitri Mendeleev developed a method for obtaining elements by the number of atoms. … Mendeleev created a periodic table of all elements known at that time. The rows of the table, called periods, contained eight elements each, the atomic mass of which increased from left to right.
