Iron objects turn reddish-brown when exposed to air because they react with oxygen in the air to form iron oxide, more commonly known as rust. This process is called oxidation and it occurs when iron is exposed to moisture and oxygen. Rust is a brittle compound that weakens the iron structure over time.
Objects that are oxidizing typically involve a chemical reaction in which they lose electrons. Examples include metals that rust when exposed to oxygen, fruits that turn brown when cut and exposed to air, and batteries that generate electricity through oxidation-reduction reactions.
Amethyst gets its color from trace amounts of iron in its crystal structure. When exposed to natural radiation and heat in the Earth's crust, these iron impurities cause the amethyst to turn purple.
Iron and steel tend to oxidize and form a black layer of iron oxide when exposed to air, commonly known as rust.
Porcelain contains impurities such as iron oxide that can cause it to turn brown when exposed to high temperatures. These impurities react with the oxygen in the atmosphere during firing, leading to the discoloration.
Iron rusts when it is exposed to oxygen and moisture, causing a chemical reaction that forms iron oxide. The green color on the Statue of Liberty is due to oxidation of the copper in the statue's protective coating over time, forming a blue-green patina called verdigris.

Iron will rust and turn reddish when exposed to water and oxygen.
Oxygen in the air reacts with the iron, making a reddish brown compound known as iron oxide. Iron is a transition metal and we havent covered them in chemistry yet so i dont know exactly why but i think the iron atom takes two oxygen's electrons to fill its outer shell.
Iron is the metal that will turn into rust when exposed to air and moisture. Rust is a reddish-brown layer that forms on iron and its alloys through a process known as oxidation.
Amethyst gets its color from trace amounts of iron in its crystal structure. When exposed to natural radiation and heat in the Earth's crust, these iron impurities cause the amethyst to turn purple.

They turn to stone when the are exposed in the sun
The black color of cast iron stoves can turn grey due to a process called oxidation. This occurs when the iron is exposed to oxygen and moisture, leading to the formation of iron oxide, which appears as a grey patina on the surface. Regular maintenance and cleaning can help prevent this color change.
Rock can turn reddish brown due to the presence of iron oxide minerals, such as hematite or goethite, that have oxidized and formed on the surface of the rock. This oxidation process occurs when iron-containing minerals are exposed to oxygen and water, causing the reddish-brown color to develop.
no you don't turn silver when your exposed to mercury, you will get numbness in your legs and arms, involuntary movement, nerve damage and brain damage
left or right turn?
