Answer: Silver is a highly unreactive metal, so it does not react with the oxygen of air easily. ... Copper is more reactive than silver but less reactive than iron. Match The Following. Question 1. Column A: Column B: … Witryna(a) Metal A is more reactive than metal B. (b) Metal A reacts with water but metal B doesn’t because metal A is more reactive than metal B. (c) Metal A reacts with Reactant X to form Substance B and Substance C I Reaction with oxygen Example: (a) Magnesium is more reactive than silver.

The reactivity series is obtained by performing displacement reactions between various metals and their salt solutions. Sodium, potassium, magnesium and aluminium are more reactive than hydrogen. Copper, mercury, gold and silver are less reactive than hydrogen.
Witryna20 lip 2015 · The electrical conductivity of elements does not really depend on its reactivity. Then silver would be one of the best insulators. It actualy depends on the number of free electrons in the atoms. So, diamond has no free electrons thus it is a good insulator whereas silver having a lot of free electrons is the best conductor. In chemistry, a reactivity series (or activity series) is an empirical, calculated, and structurally analytical progression of a series of metals, arranged by their "reactivity" from highest to lowest. It is used to summarize information about the reactions of metals with acids and water, single displacement reactions and the extraction of metals from their ores.
