H2O: Water, Bent and Polar
Two hydrogen atoms bond to one oxygen atom in a bent, polar geometry (104.5 degree angle), creating hydrogen bonding between molecules that explains why ice floats and why water dissolves so much; same molecule across all three states.
[HYDROGEN] Two of us arrive with one electron each [OXYGEN] I carry six, circling an empty pair of slots [HYDROGEN] Share a pair with me, and another share with him [OXYGEN] Both bonds bend at a hundred four point five degrees [HYDROGEN] Oxygen keeps the shared electrons close [OXYGEN] Polar covalent, negative charge on my side [HYDROGEN] Positive charge on ours, a molecule with an edge [OXYGEN] Bent, not straight, the shape decides the charge [HYDROGEN] Hydrogen bonds link one molecule to the next [OXYGEN] Weak alone, strong enough to hold an ocean [HYDROGEN] Freeze us solid, the lattice opens wide [OXYGEN] Ice floats, hexagonal lattice, lighter than the liquid below [HYDROGEN] Heat us past a hundred degrees Celsius [OXYGEN] Vapor rises, same three atoms, new arrangement [BOTH] H two O, bent and polar, holding tight [BOTH] Solid, liquid, vapor, one formula through it all [BOTH] The universal solvent, dissolving what it touches [BOTH] Every living cell depends on this bent shape
Key Concepts: Two hydrogens bond to one oxygen through polar covalent bonds | Real bond angle (104.5°) and bent molecular geometry | Hydrogen bonding between molecules explains cohesion, surface tension, and why solid ice is less dense than liquid water | Same H2O molecule across solid, liquid, and vapor | Companion to "Hydro and Oxya Make Water"
Key Words: polar covalent, bond angle, hydrogen bond, hexagonal lattice, universal solvent, H2O
Production note (duet): [HYDROGEN] and [OXYGEN] trade lines throughout; [BOTH] marks the four closing lines where the two voices join.
