Hint: This question is based on the knowledge of details of periodic tables in modern chemistry. Currently, 118 elements of the periodic table have been discovered by scientists. The further elements follow a set of rules for their nomenclature, so the next elements, although not discovered yet, can be named according to the rules of nomenclature.
Complete answer: The periodic table is a list of all the elements known to man, arranged in order of increasing atomic number and recurrent chemical properties. They are arranged in a tabular format, with a row representing an era and a column representing a group. In order of increasing atomic numbers, elements are organized from left to right and top to bottom. As a result, elements belonging to the same group will have similar valence electron configurations and thus chemical characteristics. Elements in the same period, on the other hand, will have valence electrons in ascending order. As a result, the number of energy sublevels per energy level increases as the atom's energy level rises. The first 94 elements of the periodic table are found in nature, but the remaining elements (numbers 95 to 118) have only been created in laboratories or nuclear reactors. Element 119 is thought to be an alkali metal with an oxidation state of +1. Although this element has yet to be identified, the periodic table can be used to anticipate some of its properties.
Note: The present periodic table, which we use today, is an updated version of certain models proposed by scientists in the nineteenth and twentieth centuries. On the basis of the findings of various scientists before him, Dimitri Mendeleev proposed his periodic table.
