Why is zinc more reactive than copper? The metallic bond of copper is therefore stronger than zinc, so more energy is required to break this bond in order for it to react. Since more energy is required for copper to react, we can say that zinc is more reactive than copper.
How zinc is more reactive than copper? Answer: We find, Zinc is placed higher than Copper in the Electro-chemical Series, since Zinc is more reactive than Copper. Now, the reason is that Zinc loses its valence electrons more easily than Copper to take part in a reaction.
Why is it that zinc is more reactive than iron and copper? The blue colour of copper sulphate fades and colourless zinc sulphate solution is obtained. Therefore, zinc is more reactive than copper. Aluminium has the ability to displace zinc, iron, copper from their respective salt solutions and therefore is more reactive than them.
Why is zinc more reactive? The reason are: Zinc is a more electropositive element than iron. Zinc has a bigger atomic size than that of iron and thus has more number of electrons. The fact of having more elecetrons and a ‘d’ sub shell, gives zinc a lot of hybridisation possibilities than that of iron.

How many neutrons do copper have?
All copper atoms have atomic number 29: all their nuclei contain 29 protons. But they also contain uncharged particles called neutrons. In natural copper, the atoms are of two kinds. One has 29 protons and 34 neutrons in the nucleus; the other has 29 protons and 36 neutrons (Figure 4).
Why does my copper turn blue?
When copper is oxidized by a combination of air, humid and finely divided acid and salts in the air, then a so-called patina of copper is formed. This is a basic copper (II) carbonate/sulfate mix, which has a cyan color. The reason that the color changes is that a chemical compound of copper is formed.

Why do copper coins go green?
