How do you store alkali metals?
Alkali meatls are stored in oil to stop it from mixing with the moisture in the air.Because Alkali metals are highly flammble in moist air.
A metal the name for the symbol Li?
LITHIUM!! It is a soft alkali metal with a silver-white color. Under standard conditions, it is the lightest metal and the least dense solid element. Like all alkali metals, lithium is highly reactive, corroding quickly in moist air to form a black tarnish. For this reason, lithium metal is typically stored under the cover of oil. When cut open, lithium exhibits a metallic lustre, but contact with oxygen quickly returns it back to a dull silvery grey color. Lithium is also highly flammable.
What is Saturn air like?
moist moist moist
Why do gold and platinum do not corrode in moist air?
They are both noble metals, very non-reactive, hence resistant to corrosion.
Why does gold not rust in moist air?
Yes, gold is generally very resistant to corrosion from any natural atmosphere and any aqueous solutions, except for one called "aqua regia", a mixture of concentrated nitric and sulfuric acids.

What air that gives rust to metals?
Explosure to moist air will form rust on metals.
Which metals will corrode in moist air?
Examples: platinum metals, zirconium, tantalum, niobium, hafnium, Mercury etc.
What do you mean by noble metals?
The noble metals are a group of metals that resist oxidation and corrosion in moist air. They are the opposite of the base metals, which more readily oxidize and corrode. Some of the noble metals are gold, platinum, and iridium. Aside from being corrosion resistant, they are also very expensive.
What happens if francium gets on your skin?
Francium is reactive when your skin is moist because it is very reactive with water. Francium is an alkali metal and is very reactive and violent with water.
Does lithium tarnish in moist air more quickly than potassium?
No. Lithium is the least reactive alkali metal. Within the same environment, potassium will tarnish at a faster rate.
What conditions are needed for rusting to take place?
Moist and sometimes warm environment. Also only certain kinds of metals or mixes of metals rust. For example, gold doesn't rust, but iron easily rusts.
What effect does chlorine have on moist universal indicator?
Chlorine turns moist universal indicator paper red, then bleached. It has the same effect on blue litmus paper (red then bleached). this shows it is an acidic gas and so when reacts with sodium for example (an alkali metal) makes sodium chloride (salt).

What are some property's of acids?
Sour taste, reactivity with metals, and ability to produce color changes in indicators. They sour and reacts with metal, metal carbonate and bases/alkali. Most of them are corrosive as well. They can change the color of objects like universal indicator (depending on pH, stronger acids will turn universal indicator red while the weaker ones will only turn universal indicator to yellow or orange) and moist blue litmus paper red.

They are both noble metals, very non-reactive, hence resistant to corrosion.
