How are the elements in the periodic table organized?

WebEach row i+1, contains n elements of W bytes, so row i+1 starts in memory nW bytes after the previous row. Element $[0,0]$ is at address B, and element $[1,0]$ is at address B+W*n = B+W[n(1-0)+[0-0]]. Combining those two concepts, you can find any element [I,J] using the formula.
