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.

What are the elements with atomic numbers from 58 to 71 called?

The elements with atomic numbers from 58 to 71 are called the lanthanides. They are a group of metallic elements that have similar chemical properties due to their electron configurations. The lanthanides are commonly used in various applications such as in the production of electronic devices and catalysts.
