The atomic number is the number of protons found in one atom of the given element. It is very important for many reasons. Firstly, the element itself depends on the number of protons (If you changed the number protons, then the element would change as well). Secondly, you can discover the amount of electrons using the atomic number (there are the same number of electrons in an element as the number protons, or the atomic number).
The element with a mass number of 138 and atomic number of 56 is Barium (Ba). The mass number represents the total number of protons and neutrons in the nucleus, while the atomic number indicates the number of protons. In this case, Barium has 56 protons and 82 neutrons (138 - 56 = 82).
Elements in the periodic table are placed in rows and columns based on their atomic number and chemical properties. Rows, also known as periods, indicate the number of electron shells an element has, while columns, or groups, show elements with similar chemical properties due to the same number of valence electrons. This organization helps to predict an element's behavior and reactivity based on its location in the table.
The first periodic table was developed by Dmitri Mendeleev in the mid-19th century.He wasn't the only person thinking along those lines ... both John Newlands and Lothar Meyer had proposed similar ideas However, Newlands was largely criticized and ignored at the time, and Meyer didn't make any predictions, so Mendeleev's table (which did make predictions about the properties of several as-yet-undiscovered elements) is generally regarded as the first.
