How has the periodic table changed over time
WebWe make the periodic table to help we recognize certain trends of physical and chemical properties of who elements. You need to memorize the trending. A trend is generally "it gets bigger" or "it gets smaller" sort of thing. All our trends describe the trend in two locational on the cyclically table: 1) across a row, and 2) up and blue one column.
