Unit 2: Atomic Concepts and Periodic Table (Level 1)
... We all know by now that the periodic table is arranged according to increasing atomic number. What we’re only beginning to learn is the significance of elements within the same column (vertical) and row (horizontal) on the table. Every element found within a given row, or period, has the same number ...
