Magic acid is the second most reactive Superacid behind fluoroantimonic acid. It is a superacid consisting of a mixture of fluorosulfonic acid (HSO3F) and antimony pentafluoride (SbF5). The name refers to its ability to protonate hydrocarbons, vividly demonstrated when a postdoctoral associate in the lab of George A. Olah used it to dissolve a candle.
The most reactive nonmetals are the Halogens. They are located in the second to last row on the Periodic Table from the right.
The 2nd most reactive is Cesium after Francium. If you disregard Francium because it is radioactive, then it would be Rubidium after Cesium.
fluoroantimonicacid
lithium and fluorine
Chlorine is the second lightest member of the halogen elements or group 17.
The world's most dangerous acid is Hydroflouric acid, which is actually classified as a weak acid, believe it or not. Perchloric acid gets my vote. No it isn't I thought it was carborane superacid. It was just discovered
fluorine is the most reactive

The molarity of carborane superacid will depend on the concentration of the acid solution. Carborane superacid is a strong acid with high acidity and is typically prepared in low concentrations due to its reactivity and potential hazards. Common concentrations for carborane superacid solutions range from 0.1 to 1 M.
Group 2, or the alkaline earth metals.
The order of reactivity from most to least is sodium, copper, gold. Sodium is highly reactive due to its low ionization energy, copper is less reactive as it forms a protective oxide layer, and gold is the least reactive among these metals.
