π¬ Dmitri Mendeleev's research revolutionized our understanding of the periodic table.
βοΈ The elements in the periodic table are not arranged solely based on atomic weight.
π There is a periodic recurrence of properties every seven elements (now known as every eight elements).
π The periodic table repeats every seven elements, but with less periodicity as the mass of the elements increases.
π‘ There are still undiscovered elements that don't fit into the periodic table.
𧩠The arrangement of elements in the periodic table follows patterns and can be used to predict the properties of missing elements.
π‘ The periodic table is divided into different sections based on the characteristics of elements.
π¬ Alkali metals are highly reactive and form positive ions, while alkaline earth metals have a higher reactivity and form ions with a charge of +2.
βοΈ Transition metals are found in the middle of the periodic table and include metals like iron, nickel, gold, and platinum.
π₯ Most elements are metals, which are good conductors of heat and electricity.
β‘οΈ Halogens are highly reactive gases that form negative ions and readily react with alkali and alkaline earth metals.
