What is the least metal reactive in following list gold or potassium or copper or magnesium?
Gold is the least metal reactive in the list, followed by copper, magnesium, and then potassium. Gold is known for its resistance to corrosion and chemical reactions, making it one of the least reactive metals.
Was potassium k the first metal to be discovered?
Potassium was not the first metal to be discovered. It was first isolated by Sir Humphry Davy in 1807 through the electrolysis of caustic potash (potassium hydroxide). The discovery of other metals preceded potassium, such as copper, iron, and lead.
What happens when you mix copper and gold?
When you mix copper and gold, you create a new alloy called rose gold. The copper gives the gold its pink hue, resulting in a unique and popular metal for jewelry-making. The exact color and properties of the alloy can vary depending on the ratios of copper and gold used in the mixture.
When zinc metal is placed into a solution of copper sulphate a pinky brown metal is formed but when a piece of silver metal is placed into another solution of copper sulphate no change is observed Why?
Silver is lower in the reactivity series than Zinc and therfore cannot displace the Sulphate from the Zinc. But on the other hand zinc is higher than copper, and when displacing the sulphate from the copper it changes colour due to the reaction. Reactivity series(metals): Potassium Sodium Lithium Calcium Magnesium Aluminium Zinc Iron Tin Lead Copper Silver Gold Platinum
What metals or metal compounds will not react with copper sulfate?
Metals like gold, platinum, and silver typically do not react with copper sulfate. Additionally, metal compounds that are less reactive than copper, such as zinc oxide or aluminum oxide, will not react with copper sulfate either.

Which element is the most active metal?
Potassium is the most active metal. It is highly reactive and can easily react with water to produce hydrogen gas and caustic potassium hydroxide.
What are the most important metal elements?
Answer: iron, aluminium, sodium, potassium, uranium, magnesium, copper, gold, calcium, silver etc.
Name a metal on the peridoic table?
Tungsten. Mercury. Tin. Gold. Lithium. Potassium. Calcium. Sodium. Titanium. Chromium.....................................................
Give 10 examples for metallic elements?
Examples of metals are:aluminiumbronzecoppergoldironleadmercurynickelplatinumsilverzinc
What is the reaction of Gold with copper sulfate?
At STP, there will be no reaction. Gold is much less active than copper so there will be negligible gold sulfate formed by substitution. Gold is the lowest metal in the electrochemical series, so it will not react chemically with salts of any other metal.
Is gold a metal?
Yes- gold is a metal- along with bronze and silver, copper etc.
Write the chemical symbols of the following elements gold copper potassium silver platinum and Iron?
The chemical symbols of gold, copper, potassium, silver, platinum, and Iron are Au, Cu, K, Ag, Pt, and Fe respectively.
What is example the metal?
Supposing you mean examples of metals, here is a few: Aluminium, Gold, Iron, Silver, Mercury, Platinum, Copper, Potassium, Just to name a few.
What is a type of metal?
gold,copper and silver.
