Because of Its High Reactivity Which Element
Metal chloride hydrogen. In the outermost shell it has 7 seven electrons which means that it needs just one more electron to attain an octet configuration in that shell. Comparing Halogen Reactivity Trends With Those Of The Alkali Metals Halogens Become Less Reactive Down The Chemistry Classroom High School Chemistry Chemistry The equation for reacting a metal with acid is. . A sulfur b lithium c argon d gold. The reactivity of metals is because of their incomplete outer orbitals or due to their electronic configuration. Sodium is a most reactive metal. Reactive elements release great quantities of energy when they combine with other elements. The thing that makes fluorine so reactive is its electronegativity. Some highly reactive elements are fluorine sodium potassium lithium and oxygen. The most reactive metal is francium the last alkali metal and most expensive element. Because it isnt below carbon in t...
