19.1: Properties of Transition Metals and Their Compounds

Rest is History on Instagram: "When lithium burns, its atoms react rapidly with oxygen in the air, forming lithium oxide and releasing intense heat. Because lithium is an alkali metal with a single valence electron, it reacts extremely easily, which is why it ignites with a bright crimson-red flame. During combustion, lithium atoms lose electrons, oxygen gains them, and the energy released shows up as both heat and that signature red color caused by excited lithium electrons dropping back to low
