What elements are on the staircase on the periodic table?
Metallic character increases form right to left across a period on the periodic table, and from top to bottom down a group. The alkali metals in group 1 are the most active metals, and cesium is the last element in the group for which we have experimental data.
The staircase line indicates the position of the metalloids in the Periodic Table.
What is the purpose of drawing a staircase on a periodic table?
What group of elements lies on the stair dividing line?
Along the stair-step line are the metalloids, which have properties of both metals and nonmetals. The nonmetals are located to the right of the stair-step line on the periodic table.
