Tom the Atom, Book 16: Comics

You, Mary, and Henry go to visit Tom-the-Atom World to meet Silicon and learn about Semiconductors. This time they visit the town where atoms live. They stop at the beautiful and wealthy neighborhood of the Semi-Metals. The community is small. Tom-the-Atom calls out to Silicon. He is in the Periodic Table in Column 14 or Group 4A. I.e.., he has 4 valence electrons in his outermost shell/subshells. He is the 3rd row, just below that Tom-the-Atom, Carbon. Silicon is in the 3rd row (or Period), meaning he has 3 shells. Silicon is dressed very wealthily and shows us his outside market. Easy to figure it out how versatile and essential it is for human.
