“A single covalent bond!” Electra announced. “They just formed Cl₂. See? Not every bond requires giving up something. Sometimes, you just share. That’s the secret of molecules.”

In the bustling city of Átomo, nothing ever stayed still. Marco, a restless 10th-grade student, stared at the periodic table on his wall. “Why do I need to know this?” he sighed, slumping over his desk.

They landed on a giant staircase. Each step glowed a different color: red, orange, yellow, green, blue, violet. Fisico Quimica 10 Ano

“The energy change of a reaction equals the heat absorbed or released. Endothermic takes energy from the surroundings; exothermic gives it away.”

“Boyle’s Law!” Marco shouted, remembering his notes. “At constant temperature, pressure times volume is constant! P·V = k!” “A single covalent bond

Suddenly, a crack split the sky. A massive, greedy ion named Sodium (+1) was chasing a terrified Chlorine (-1). Sodium wanted to steal an electron.

They zipped out of the atom and into a dark forest. Two lonely atoms stood facing each other: a chlorine with seven arms (valence electrons) and another chlorine with seven arms. Not every bond requires giving up something

“They are,” Electra whispered. “Each one wants an octet—eight electrons in their outer shell. The rule of stability.”
