What else can I help you with?
Is aluminum reactive than gold?
Yes, aluminum is more reactive than gold. Aluminum is more prone to oxidation and reacts readily with oxygen in the air, whereas gold is a noble metal and does not easily react with other elements.
What is the least reactive metal in water?
Of the popular metals, platinum. Not sure about the rest.
Are iron and oxygen highly reactive elements?
Iron is reactive but not highly reactive, while oxygen is highly reactive. When iron reacts with oxygen, it forms rust. Oxygen is highly reactive because it readily forms bonds with other elements, making it important for various chemical reactions.
Which element would be LEAST reactive with oxygen?
Noble gases, such as helium or neon, would be the least reactive with oxygen due to their full valence electron shells, which make them stable and unlikely to form compounds. Among other elements, metals like gold and platinum also exhibit low reactivity with oxygen, as they do not readily oxidize. In contrast, alkali and alkaline earth metals are highly reactive with oxygen.
What is the lest reactive metal in the world?
Gold is considered the least reactive metal in the world because it does not easily corrode or react with oxygen, water, or most acids. This property makes gold highly resistant to tarnishing or rusting, which is why it is often used in jewelry and other decorative items.
Which is less reactive gold or platinum?
Platinum is less reactive, by reacting with aqua regia only in the hot while gold not. Platinum potassium cyanide is not known while Gold potassium cyanide is obtained quite simply. In contrast, Platinum is somewhat lower on the electromotive scale - 1.2v against 1.5-1.6v for gold
What metal is expected to be least reactive gold potassium sodium or lithium?
Gold. The other three, as Group 1 alkali metals, are highly reactive.
Is copper more reactive than gold?
Even though gold and copper are in the same family, copper is much more reactive than gold. This is why Copper rusts more than gold, and why there are so many copper compounds (IE copper silicate...). Copper is higher in the family, giving it these characteristics.
Is argon more reactive than oxygen?
No, argon is not more reactive than oxygen. In fact, argon is a noble gas and is very non-reactive, while oxygen is a highly reactive element that readily participates in chemical reactions.
Does gold oxidize?
Gold does not oxidize, meaning it does not react with oxygen in the air to form rust or tarnish like many other metals. Gold is a noble metal, which means it is very resistant to corrosion and oxidation, making it suitable for use in jewelry and other applications where tarnishing is a concern.
Is nitrogen more reactive than oxygen?
No, oxygen is more reactive than nitrogen. Oxygen readily forms compounds with other elements, while nitrogen is relatively inert under most conditions.
What element is highly malleable and almost non reactive?
Gold is highly malleable and almost non-reactive.
