Gold is a chemical element with the symbol Au and atomic number 79. It is a dense, soft, malleable and ductile metal with a bright yellow color and luster, the properties of which remain without tarnishing when exposed to air or water
It is very important for indians as they use it in every occation like weddings,functions,festivals etc.there is a history of its popularity.it has unique chemical properties which makes it valuable and the superior of all metals.
Gold is recycled more than iron as it is a lot more expensive than iron, meaning it would be a waste to throw it away. Also it is a lot less common and more valuable.
Iron is more reactive than copper
because it can make steel an even tougher and harder steel compound.
The investigator will discover that potassium (K) is much more reactive than silver (Ag). Silver is a transition metal (d block elements) while potassium is an alkali metal. The alkali metals are in Group 1 of the periodic table, and elements on the left side (and going down) are quite a bit more reactive than those in the middle, where silver is. It turns out that potassium has a lone valence electron, and this element want to loan that electron out in a chemical bond very badly. That makes potassium much more likely to form a chemical bond than silver, and makes it more reactive.
it is used for making metals such as iron ingots and gold ingots
Iron can be used to get copper from Copper Sulfate because it is more reactive than Copper (higher up in the reactivity series).
Fortunately, iron ore is much more common than gold ore; gold may be pretty but iron is used to make steel.
No
Sacrificial protection is only effective if the metal used for sacrificial protection is more reactive than Iron in the reactivity series. Since gold is one of the least reactive metals in the reactivity series, it would not get oxidized in the place of Iron. A more reactive metal than Iron, e.g. Zinc, is used as the Zinc metal would oxidize in the place of iron, thus preventing Iron from rusting.
One reason is that gold is considerably denser than iron and therefore sinks more consistently to the bottom of a shaken pan. Another reason is that iron rarely occurs in nature in elemental form, while gold relatively often does occur naturally in elemental form.
Iron is more reactive than copper
Iron is more reactive than copper
In a short answer No. But I can't really explain why.
Pure gold is too soft to be used in jewelry.
Because iron is a more reactive metal than copper.
Iron became more widely used than bronze because it was more readily available and easier to extract from ores. Iron also had other advantages over bronze, such as being harder and more durable, making it better for tool and weapon production. Additionally, iron was cheaper and more abundant than bronze, making it accessible to a larger number of people.
It was gold and iron
Platinum is slightly harder than iron and iron can easily scratch gold. Platinum is also the least reactive metal and may have been used by early man before copper.
