Gold is more reactive than mercury then why it comes before the mercury.
Answers
Answer:
Gold is more reactive so, it comes before.
Coz reactivity series is in decreasing order..
Explanation:
Reactivity Series of metals Chart
In the reactivity series, as we move from bottom to top, the reactivity of metals increases. Metals present at the top of the series can lose electrons more readily to form positive ions and corrode or tarnish more readily. They require more energy to be separated from their ores, and become stronger reducing agents, while metals present at the bottom of the series are good oxidizing agent.
We can summarize the reactivity of metals in a reactivity series chart as shown below:
Lithium Li Displaces H2 gas from water, steam and acids and forms hydroxides. Electrolysis
Potassium K
Strontium Sr
Calcium Ca
Sodium Na
Magnesium Mg Displaces H2 gas from steam and acids and forms hydroxides.
Aluminium Al
Carbon C Included for comparison.
Manganese Mn Displaces H2 gas from steam and acids and forms hydroxides. Smelting with coke
Zinc Zn
Chromium Cr
Iron Fe Displaces H2 gas from acids only and forms hydroxides.
Cadmium Cd
Cobalt Co
Nickel Ni
Tin Sn
Lead Pb
Hydrogen gas H2 Included for comparison.
Antimony Sb Combines with O2 to form oxides and cannot displace H2. Heat or physical extraction methods.
Arsenic Ar
Bismuth Bi
Copper Cu
Mercury Hg Found free in nature, oxides decompose with heating.
Silver Ag
Palladium Pd
Platinum Pt
Gold Au
