The reactivity series is a list that shows the order of reactivity of some common metals. Calcium (Ca) Reacts vigorously with strong heating. Brick red flame observed and white solid formed. 2Ca + O 2 ...

Since the discovery of gold an estimated 5,000 years ago, metals have played an integral part in the lives of human beings. We all know, almost instinctively, what consitutes a metal and what doesn't, ...

A new approach reveals unexpected ways oxygen can bind to rare metals. Iron plays a central role in how the body uses oxygen. In hemoglobin, it binds dioxygen, a pair of oxygen atoms, allowing blood ...

Alkali metals like lithium, sodium, and potassium are famous for their dramatic reactions with water, from fizzing to full-on explosions. Their single valence electron makes them eager to react, ...

Gallium’s quirky liquid-state properties have pushed that element into the scientific spotlight recently, as researchers have tapped the liquid metal for applications in stretchable electronics and ...

Lithium-metal (Li-metal) batteries show great potential for packing more significant amounts of energy than the current lithium-ion batteries. For example, a Li-metal electric battery in a car could ...

Iron and oxygen bind together throughout the body. Most famously, iron binds dioxygen, or two oxygens paired with each other, in hemoglobin that transports oxygen through blood. But iron-oxo compounds ...
