[Verse 1] Two nitrogens locked in a triple-bond vow, strongest bond in the whole periodic crowd, Haber and Bosch crank the heat, crush the air, iron catalyst forcing what nature does with care, nitrogenase works soft, no furnace, no strain, molybdenum-iron cluster splitting the chain, ammonia to nitrite, nitrite turns nitrate, denitrify back to gas — the cycle won't wait [Chorus] Five valence dancers: N, P, As, Sb, Bi, sharing three electrons, reaching for the sky, six on the ledge where Group Sixteen stays, O down to Po, grabbing two always, count your outer shell, that's the mnemonic key, groups tell you the bonds before you even see [Verse 2] Lightning cooks N2, spits out NO by chance, engines add more, smog thickens the glance, Ostwald burns ammonia on platinum gauze, NO to NO-two to nitric acid — that's the law, Phosphorus wears three coats: white one glows and burns, red's a polymer chain, black's the sheet that turns like graphite, PO-four rungs hold the DNA spine tight, ATP's third bond is the flashbulb of life, fertilizer PO-four feeds the wheat, feeds the corn [Chorus] Five valence dancers: N, P, As, Sb, Bi, sharing three electrons, reaching for the sky, six on the ledge where Group Sixteen stays, O down to Po, grabbing two always, count your outer shell, that's the mnemonic key, groups tell you the bonds before you even see [Verse 3] Arsenic apes PO-four, sneaks into the cell, stalls the engine running your body's carousel, yet gallium arsenide lights diodes with a grin, wider bandgap chip than silicon's kin, Bismuth's the soft giant, pink and rarely cruel, Pepto's own subsalicylate — barely toxic, mild by rule, now Oxygen: ground state's triplet, two spins unpaired, excite it once, flip a spin — singlet, short and scared, that lone oxygen bleaches membranes where it flies [Bridge] Ozone's born when ultraviolet splits O2 in half, loose oxygen finds a partner, forms the shield we laugh under — till CFCs drift and chlorine breaks free, one chlorine chews ten thousand ozones easily, that's Module Ten's shadow haunting stratosphere air. Now the hydrides: water clings with bonds so rare, H2O boils highest, hydrogen-bond glue, but Se and Te grow heavier, so boiling points climb too, acidity flips backward as the bond gets weak, H2Te's the sourest, water's the meek, Pauling's rule: more oxygens not bonded to H, the stronger the acid — count them, gauge the depth, H3PO3 hides one hydrogen on P itself, so only two protons leave — diprotic, nothing else [Verse 4] Sulfur crowns itself, eight atoms in a ring, oxidation states from minus-two to plus-six can swing, Contact Process burns it, vanadium clears the way, SO2 to SO3, water drinks it — sulfuric today, Selenium guards proteins, parries peroxide's thrust, Tellurium panels harvest sunlight from cadmium dust, Polonium-210 — alpha particles, a deadly kiss, heavy elements teach caution wrapped in atomic bliss
