Names of three metals which do not corrode?
The three metals that do not corrode are gold, silver and platinum.
Do the alkali metals have the ability to tarnish?
By forming their oxides, the alkali metals tarnish very quickly with respect to many other metals.
Why do metals corrode differently?
Metals corrode differently due to variations in their chemical properties, environmental conditions, and exposure to corrosive agents. Factors such as composition, presence of protective layers, and electrochemical reactions can influence the rate and type of corrosion for different metals. Additionally, the pH level, humidity, and temperature of the surrounding environment can also impact how metals corrode.
Why do metals need to be protected against rust and tarnish?
Metals need protection against rust and tarnish because these processes can weaken the metal, leading to degradation and structural integrity issues. Rust is a form of corrosion that occurs when iron reacts with oxygen and water, while tarnish is a result of metal reacting with sulfur compounds in the air. Both can compromise the appearance and functionality of the metal.
How does metal react to bleach?
Metal can react with bleach (sodium hypochlorite) in various ways, depending on the type of metal. Some metals, like aluminum and iron, may corrode or tarnish when exposed to bleach, leading to oxidation and degradation. Stainless steel is generally more resistant but can still be affected, resulting in pitting or discoloration. It's important to avoid mixing bleach with metals in cleaning or maintenance applications to prevent damage.
What are synonyms for tarnish?
Some synonyms for tarnish include stain, blemish, and dull.
Does gold tarnish as it ages?
No, gold does not tarnish as it ages. Gold is a non-reactive metal, so it does not corrode or tarnish like other metals. However, its appearance can change with time due to scratches or other forms of wear.
Do some metals corrode?
Yes it does. but not all metals.
Why does metals corrode more quickly near the sea?
Because some metals are reactive and corrode in sea water
Do acids corrode some metals?
Yes it does. but not all metals.
Is most metals reactive.?
Most metals are reactive to some extent, but their reactivity varies. Some metals, such as gold and platinum, are less reactive and do not easily tarnish or corrode. Other metals, like sodium and potassium, are highly reactive and must be stored in oil to prevent them from reacting with moisture in the air.
Does gold tarnish?
Gold does not tarnish. It is a highly stable and non-reactive metal, which means it does not rust or corrode like some other metals when exposed to air or moisture. This is one reason why gold is valued for its durability and long-lasting shine.
What conditions make metals corrode?
Metals corrode when they are exposed to moisture, oxygen, and other chemicals in the environment. This exposure can lead to chemical reactions that degrade the metal's surface over time, causing rust or tarnish to form. Factors such as temperature, acidity, and the presence of pollutants can also accelerate the corrosion process.

What metal decomposes?
Most metals do not decompose in the traditional sense, but rather corrode or tarnish over time due to exposure to air or water. Some metals, like alkali metals, can react violently with water, leading to decomposition into their elemental components. Additionally, highly reactive metals such as magnesium and aluminum can decompose at high temperatures through a process known as thermal decomposition.
Do acids corrode metals?
Yes. Some can only corrode soft things, and some can corrode everything. But in short, all acids can corrode something. It only gets dangerous if the acid can corrode you.
