Tom-the-Atom represents the Carbon Atom, the most crucial atom in the Universe. A series of illustrated science books for children and adolescents. The young reader will become familiar with the world of atoms, which make up all the material in the Universe; the Earth, the planets, the stars, and you and me. The young reader is invited to become part of the World of Atoms and to develop his/her understanding of how atoms form everything. Tom the Atom, Book 10: A day at the museum: Henry and his friends discover electricity! Henry and his classmates visit an exhibit at the Lawrence Hall of Science --in Berkeley, California-- on electricity. Children learn the concept of electricity, a current of metal's valence electrons. In metallic atoms, the valence electrons are so loose that they can move from one atom to another when a pressure called voltage difference is applied to the metal. Electricity is flux or flow that we call a current of "free" electrons.

Henry and his classmate visit an exhibit at the Lawrence Hall of Science in Berkeley, California. In their museum's visit, they reinforce the concept of valence electrons or "hands." In doing so, children introduce the idea of electricity associated with metals and valence electrons. Electricity is a property of the atoms that can be classified as Metals (three groups: Metals, Semi-Metals (or Metalloid), and Non-Metals were introduced in Book 6). In the Metals group, when many atoms are together, their valence electrons are so loose that they can move to an outer "band" called Conduction Band. Valence electrons there just move from atom to atom, generating a current of electrons. As water running in a hose!Electricity is a flux of electrons (like the water in a hose) that we call a "current." Electrons freely flow through the metal under the influence of a force that we call a Voltage difference (like water pressure in a hose). The Metals are "Electrical conductors."

You, Henry, and Mary learned that atoms belong to 10 families. That they are a total of 92 atoms. Only 92 in the entire Universe! But each one has many twins (tuples). In shape, atoms are round. They have a tiny, massive belly full of Protons and Neutrons. Outside their nucleus or belly, they have from one to 7 belts filled with Electrons. Protons are positive, neutrons do not have a charge, and electrons are negative. The number of protons in their belly equals the total number of small electrons in their shells (or belts). The number of protons and neutrons in their belly gives their weight. The number of shells determines their size. All shells are full, but the last one that can be or not complete. The electrons in the outermost shell are called valence electrons. The number of electrons in their outermost shell (usually from one to eight) dictates the atoms' Character. Tom calls those valence electrons "hands" and the lack of them in that outermost shell called "empty sleeves."

Tom the Atom, Book 3: Bonds make a world fond.GOAL: To introduce the concept of Covalent Bonds.Henry, Mary, and Tom-the-Atom hold hands and say the magic words that make them very small and allow them to visit the world of the atoms. The shell closest to the nucleus can accommodate up to two electrons. The next shell can accommodate eight electrons, and the one after that can have eighteen electrons. However, we can say that, in general, if the atom is tiny (Hydrogen and Helium), they will have only one shell, and it can accommodate up to two electrons (one for Hydrogen and two for Helium). If the atom is larger, the shells are subdivided into subshells, and the outermost subshell can accommodate up to eight valence electrons. Tom-the-Atom calls the valence electrons in the outer shell "hands." If the outer shell is not full, that shell will have "empty spaces" waiting to be filled by other atom's electrons. Tom-the-Atom calls those empty spaces "empty sleeves." One "hand" and one "empty sleeve" shared with another atom makes a bond. Tom-the-Atom introduces to Henry and Mary the concept of Covalent Bond between atoms. A covalent bond is defined as "a double handshake" between two atoms' outermost shells (orbital). Tom-the-Atom (Carbon), for example, has four "hands" (or valence electrons) and four "empty sleeves" (or missing electrons in his outermost shell, to a total of eight. One Covalent Bond is formed when two atoms share one "hand" and one "empty sleeve" simultaneously to produce a firm "handshake" between two atoms-each atom "hand" slides into an "empty sleeve." We represent this "single bond" between atoms X and Y by X-Y. Tom-the-Atom can also form four single covalent bonds with four different atoms, in that case, the total number of handshakes involving Tom-the-Atom is four.

GOAL: To introduce the Carbon atom (or "Tom-the-Atom"), who will be our host to present the readers to the world of atoms.Tom-the-Atom is discovered living in a beautiful shell on the beach at Half Moon Bay, south of San Francisco, CA where Henry and his sister Mary are walking, with their father and their dog, Bonita, on a nice warm day--one of those beautiful Indian Summer days--on a Tuesday after school, in the month of October. Henry and Mary bring the shell they found to Henry's bedroom where Tom-the-Atom, exiting the shell, becomes an instant friend of Henry and Mary. Tom-the-Atom entices Henry and Mary to visit his world once a day after school, and he proposes to introduce them to his siblings and extended relatives who belong to the 10 different families of atoms (including his own family) as described in the "Periodic Table." They will learn how everything alive and not alive (organic and inorganic) in our Universe is made of tiny atoms, which by shaking hands they form bonds among themselves to form molecules!The readers will learn an exciting new concept related to the atoms in each book.

Noble Gas atoms do not interact with other atoms, because their valence shell (or subshells) is FULL. Members of the Noble Gases family have all their shells, including their outermost valence shell full of electrons to their rim. They do not need to "handshake" with any other atom to borrow or give away electrons; that is why they are not reactive and do not need to shake hands! They do not form chemical bonds with anyone. They are a family of 6 existing siblings. In the family of Noble Gases, the atom's outer shell has no "empty sleeve." The concept of inert gas is explained. The idea of shell and sub-shells and how the sub-shells are arranged, when atoms have more than 3 shells, is revealed.

You, Mary, and Henry met Gold, an atom from the family of the Transition Metals. However, he and his nine siblings form a small subfamily called the Noble Metals. The atoms of the subfamily(that belongs to the Transition Metals family) are very reactive as atoms but not asmetals. As metals, the Noble Metals' atoms are happy and feel complete. They are severalreasons, but the most important is that their s subshell (which suffers a contraction (LanthanideContraction)) is closer to the atom's belly.The outermost d subshell is full. That property of the Noble Metals (shrunken radius and innervalence s subshell) allows humans to use the Noble Metal as a facilitator of electron transferbetween two reacting molecules/atoms in a process called "Catalysis". Noble Metals do sowithout messing (reacting) with those compounds. Still, they just help their electrons to movefaster from molecules to compounds through them: they make the reaction go quicker, and aCATALYST had born!Gold and Platinum, Gold and his brother, Platinum, are the most stable atoms, and whencombined with tuples, they form bulk metals. In general, Metals are attacked by Oxygen andwater, transforming back the metal to Metal Oxides. But Oxygen and water cannot attack theNoble Metals. They remain shiny and beautiful; that is, they do not "tarnish". Particularly, Gold has that pretty color and high luster. Noble Metals have the highest electronegativity(want to grab electrons from other atoms) among the Transition Metals. While TransitionMetals have mostly positive Oxidation States (lose electrons), Noble Metals can have negativeOxidations States. But, remember, although the atoms are reactive, the bulk metals are iner
