what is reactivity series of metals class 8

The elements in period two differ in properties from their respective group elements due to the small size and higher value of electronegativity. Water (H 2 O) is a polar inorganic compound.At room temperature it is a tasteless and odorless liquid, nearly colorless with a hint of blue.This simplest hydrogen chalcogenide is by far the most studied chemical compound and is described as the "universal solvent" for its ability to dissolve many substances. Metals which fall below hydrogen in the reactivity series do not react with dilute acids. While metals such as zinc, aluminium, magnesium, calcium, etc. The d 9 electronic configuration of this ion gives three electrons in the two degenerate e g orbitals, leading to a doubly degenerate electronic ground state.
