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.
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.
Aanya and Vihaan visit the Element Library and discover the periodic table — a secret map that organizes elements into groups and periods and helps explain why they behave the way they do.
El número atómico (Z) es la cantidad de protones e identifica el elemento; en un átomo neutro, protones = electrones. El número másico (A) es protones + neutrones. Los isótopos son átomos del mismo elemento con el mismo número atómico pero distinto número de neutrones (y distinto número másico). Un símbolo de nucleido muestra A y Z con el símbolo del elemento.
