Science stories kids actually want to read
Opening your story…
Riya and Kabir enter Ionora, the Kingdom of Ions, with their robot guide Sparky. Through glowing castles, electron-exchange bridges, and crystal lessons, they discover how atoms become charged: lose an electron to form a cation, or gain an electron to form an anion.
At a science fair booth called The Atom Detective Agency, Anika and Rohan learn atomic number, mass number, and isotopes — and how atoms of the same element can have different numbers of neutrons.
Tara and Neil explore the Atomic Explorer and learn Bohr’s atomic model — electron shells K, L, M, and N — plus electronic configuration, valence electrons, and how valency helps atoms combine.
La atomicidad es el número total de átomos presentes en una molécula (H₂ = 2, O₃ = 3, H₂O = 3, P₄ = 4, S₈ = 8). La valencia es la capacidad de combinación de un átomo (H = 1, O = 2, N = 3, C = 4). La atomicidad cuenta átomos en una molécula; la valencia explica cómo se unen los átomos para formar sustancias.
