Q2: What do you understand about the Periodic Table?
Answer: The Periodic Table is how researchers have arranged the 100+ elements that constitute all matter. Dmitri Mendeleev, a Russian chemist, proposed it in 1869. Mendeleev arranged the elements in order of the mass of their electrons, unlike prior attempts to organise the elements by characteristics. He also left empty spaces for items that had yet to be identified. As a result, he was able to forecast what those yet-to-be-discovered elements will be like. The elements are arranged in the Periodic Table in two ways: Periods: these run from left to right across the table. The number of protons in the nucleus of the atom rises by one as we proceed in this direction. Groups: Each vertical column represents a group. Because they usually have the same amount of electrons in their outer shell, groups comprise elements with similar properties.
