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.
