1. Make your own periodic table using the hypothetical elements that are given in the clues.

2. Explain the word/s that will be formed if you arrange the symbols of the elements correctly.

a) P and Pr both have one electron each. Pr has a bigger atomic size.

b) Od, Ri, and E are in the same series as P, C, and I. In terms of atomic size, P is the biggest while C is the smallest. E is a metal while I is a non-metal. Od is smaller than Ri in atomic size.

c) O has a bigger atomic size than E in the same group. Es is also a bigger atom than C in the same group. R is more nonmetallic than Pe but more metallic than Ti.
