    Instead of using the mnemonic Copper, Mercury, Saves, Gold we could write Copper, Makes, Silver, Gold.

    What are the principles of chemistry that determine which elements are more reactive?

      Hey there!
      A quick recall
      An atom consists of protons and neutrons which
      make up the nucleus and electrons which orbit
      the nucleus in specific shells. (Think of our
      solar system- the sun is the nucleus and the
      orbit of different planets as shells...the
      difference is that there can be more than 1
      planet(electron) in 1 orbit.)

      Basically, the valence electrons
      note; no. of electrons in the last shell try their best to achieve an octet(valency), and
      no. of shells(energy levels) determine how reactive an element is.
      basically, the nuclear force exerted on the outermost electrons by the nucleus is an atomic scale understanding of reactivity.

      As @Uma Chatterjee has mentioned, you will learn more about this later.
      This is just a quick review,
      Hope this helps!
      Onward!

    onwards, we can take any salt of copper, right?
    not just its sulphate
    If sulphate is the best choice, why is it?

      You can take any salt of copper, like nitrate, chloride, etc.
      However, copper sulphate is an easily obtainable substance(blue vitriol). Other salts need to be prepared.
      Also, copper sulphate when reacted with iron shows a distinctive color change. When an iron nail(grey) is dipped in a copper sulphate solution (blue) a brown coating forms over the nail (copper) and the solution turns green (iron sulphate).

      Happy to help:)

    Can a reactivity table be made with respect to non-metals as well, considering electro-negative property as in metals( higher the electro-positivity higher its reactivity)?

    But why do more reactive metals displace the less reactive ones? Is there something happening at the level of atoms?

      The Reactivity of metals depends on their valence electrons. The more the valence electrons, more the reactivity. Now, if we see the electronic configuration of both the elements-
      Iron - 2,8,14,2
      Copper- 2,8,18,1
      As we can see Iron has more reactivity because it as more valence electrons than Copper.
      I hope this clears your doubt.
      Do tell me if I am wrong, or you have any other doubt.

    Although magnesium chloride doesn't have any chlorine molecule, why is its formula MgCl2 and not MG2Cl?

    Sir, Carbon is a Non-Metal, right? Then why is it shown in the reactivity series of metals?
