M1-A · Room Inside · Emo

[Verse 1] My sleeve is caught against the desk, The window lets the morning in. The desk has mass and takes up space; The light falls warm across my skin. That light is not another kind of matter. The air I cannot see still is. Mass tells how much matter's present; Volume tells the space it fills. [Chorus] There's a world inside the ordinary, Smaller than the eye can know. Protons positive, electrons negative, Neutrons neutral at the core. [Verse 2] Protons, neutrons in the nucleus, Nearly all the mass held there. Electrons in the cloud around it, A model drawn with room to spare. Neutral means the counts are equal: Protons match electrons one for one. Same protons, different neutron totals— Isotopes; the element stays the same. [Final Chorus] There's a world inside the ordinary, Smaller than the eye can know. Protons positive, electrons negative, Neutrons neutral at the core.
