Who found a relationship between the wavelengths of x-rays and the atomic number of elements?
Henry Moseley found the relationship between the wavelengths of x-rays and the atomic number of elements. He proposed that the atomic number of an element is better defined by the number of protons in the nucleus rather than by its atomic mass.
What is the difference between isobar and isotope?
isobars are elements with same mass numbers (Atomic Mass) and different atomic number (number of proton or electron)
What is the relationship of two isotopes of an elements nuclei?
Isotopes of an element have the same number of protons in their nuclei (same atomic number) but different numbers of neutrons, resulting in different mass numbers. This difference in neutron content gives each isotope unique physical properties such as stability, radioactivity, and atomic mass.
How are the actinide series elements created?
Elements with atomic numbers 89-94: natural elements.Elements with atomic numbers 95-98: artificial elements but they are also discoverd in nature as ultratraces.Elements with atomic numbers 99-103: artificial elements.
Who was the Russian chemist show a definite relationship between chemical properties and atomic weights of the elements?
Mendeleev

What are the elements below uranium?
Below uranium in the periodic table are all the elements with atomic numbers between 1 and 91.The atomic number of uranium is 92.

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.
What is the relationship of two isotopes of an elements nuclei?
Isotopes of an element have the same number of protons in their nuclei (same atomic number) but different numbers of neutrons, resulting in different mass numbers. This difference in neutron content gives each isotope unique physical properties such as stability, radioactivity, and atomic mass.

What is the relationship between the electron configuration of an element and the period in which that element appear in the periodic table?
Electron configuration is the arrangement of elements according to their increasing atomic numbers whiles period is the arrangement of elements according to the increasing number of valence electrons.
What is The periodization?
The periodic law is:When elements on the periodic table are arranged by atomic number, relationships and similarities in properties can be seen.This means that the properties of the elements are periodic, or recurring, functions of their atomic numbers. Because of this phenomenon, it is possible to construct a table that graphically reflects the relationship between the properties and atomic number. This table is called the Periodic Table.
How are the atomic numbers and the atomic masses of the elements related to how the elements are arranged on peridoic table?
Elements are arranged in a periodic table by atomic number, lower on top and left. Atomic masses have no direct relationship to the arrangement of atoms, although generally atoms with higher atomic numbers will have higher atomic masses. (There are at least three exceptions for atoms with atomic numbers differing by 1.)
How elements arranged according to increasing atomic number?
atomic numbers
Isotpes of elements have different?
atomic numbers
