The staircase along the periodic table is called the "staircase of metalloids" or "zigzag line." It separates the metals on the left from the nonmetals on the right and helps to distinguish between the properties of elements in different regions of the table.
As you go from left to right of the staircase, the number of electrons on the valence shell increases (not counting the transition element). Anything left of the staircase the elements lose electrons, and anything right of the staircase gains electrons.I hope that helps!!!!!
While history is vague as to the exact date of the first spiral staircase,it is widely accepted that spiral staircases appeared in the middle ages as a defensive structure inside castle walls.The concept was that soldiers would man the staircase inside the tower wall,and shoot downward at any intruders affording them a distinct advantge.Great question!
