TOM THE ATOM, BOOK 7
Standing at my podium, I am trying to watch my Sodium!
GOAL: You will meet Sodium (Na). Lithium’s brother. Tom-the-Atom teaches you how to use the Periodic Table.
Tom-the-Atom calls on Sodium from the family of the Alkali Metals, in Column 1 of the Periodic Table. Sodium is a brother of Lithium. Sodium, Na, is a soft, silvery-white, highly reactive metal. He has a single electron in its outermost shell that it readily donates, forming a positively charged Atom—the Na+ Cation or Sodium-ion. Sodium and Lithium have very similar characters. Tom the Atom adds the concept of dissolution of ionic salts in water.
You will guess the Atom’s character, just by looking at which column (total of 18) and Row (total of 7) the Atom is placed in the Periodic Table.
