Cubical-Stair Periodic Table

Sarthak Gupta's Cubical-Stair Periodic Table (Into a Whole New Dimension):

"Looking at the Modern periodic Table, somethings always bug you. The huge gap between the s and p-block when they should be side by side. The whole f-block floating around in air when it should be there in period 6 and 7. So why not experiment with shapes and structures and come up with something more space efficient?

"The cubical Periodic table paves the way taking the periodic table into a whole new dimension. Yes! from the 118 squares, we are going to transition into 67 cubes stacked onto each other like stairs."

The Cubical-Stair Periodic Table Explained:

• The table is made up of 67 cubes stacked onto each other, having three sides exposed(top, left and right)
• The top faces contain s and p-block elements
• The left side faces contain d block and right side faces contain f block
• There are two different Major Groups: A and B
• Major Group A is divided into 14 minor groups (from -1 to 12) and Major group B is divided into 8 minor groups (from 3 to 12)
• Major Group A applies to s, p & f-block. Major Group B is exclusively for d-block.
• To go down a group we follow the arrow and descend the stair in the given direction

• Although being 3 dimensional, it can be easily represented in 2 dimensions in the form of trisected hexagons
• All the elements of the same period lie in the same line (unlike MPT where f-block elements had to be depicted separately due to lack of space).
• Viewing the table from 3 different directions makes only one or two blocks visible:

1. From top: s & p-block
2. From left: d-block
3. From right: f-block

• This helps in diffrentiating between the blocks easily
• The disturbing gap between s and p-block of traditional periodic table is not simply there. All advantages of Modern Periodic Table remain conserved.
