It tells you how many protons an atom of an element has. It is the basis of the arranegement of the Periodic Table and has taken the scientific world a long time to discover. About 1860 C. E. Mendeleyev published the first such table.

Why do we need atoms?

According to modern Periodic Table Atomic numbers are the fundamentals in order to explain the properties of an atom.One thing more and that is the concept of isotopes also make the atomic masses less strong to explain atomic properties which has no effect on atomic numbers.

By how many units do that atomic numbers of these two elements differ?

To determine how many units the atomic numbers of two elements differ, you need to know the atomic numbers of both elements. The atomic number is defined as the number of protons in an atom's nucleus. Once you have the atomic numbers, you can simply subtract one from the other to find the difference in units. If you provide the names or symbols of the two elements, I can give you the specific difference.

Why do elements of even atomic numbers are more abundant than that of odd numbers?

Elements with even atomic numbers are more abundant than those with odd atomic numbers because of nuclear stability. Elements with even atomic numbers have equal numbers of protons and neutrons, resulting in more stable nuclei due to pairing effects. This stability makes it easier for elements with even atomic numbers to be formed through various nuclear processes, leading to their higher abundance compared to elements with odd atomic numbers.

Can you have a fractional atomic number?

No, fractional atomic numbers do not exist in the context of the periodic table. Atomic numbers represent the number of protons in an atom's nucleus, and since protons are whole particles, atomic numbers must be whole numbers. However, in certain advanced theoretical contexts, such as in particle physics or discussions about isotopes, concepts may arise that involve fractional charges or effective numbers, but these do not change the fundamental nature of atomic numbers as integers.
