What characteristics are shared by all alkali metals and alkaline earth metals?
They are highly- reactive metals
Why the melting point boiling point and densities of alkaline earth metals are higher than alkali earth metals?
Alkaline earth metals do not exist , only alkali earth metals
Why are neither the alkali metals nor the alkaline earth metals found in nature?
Because these metals are very reactive and readily form compounds.
What are characteristic property of the alkaline earth metals?
they are harder than alkali metals
Why are neither the alkali metals nor the alkaline-earth metals found uncombined in nature?
Because these metals are very reactive and readily form compounds.
What makes ferrous metals rust?
Exposure to water or dampness
What are the Name of object which rust?
Rust is a specific term used for the oxidation of Metals on exposure to air.
Name a disadvantage of ferrous metals?
They generally oxidize with exposure to the moisture in air, producing rust.
What is fanconi syndrome?

Why did Karl Scheele die?
Cumulative exposure to mercury, lead and their compounds, and other metals caused him to die
How metals change due to exposure to the air?
Some metals, namely iron, oxidize (that is the metal loses electrons) in the presence of air. This causes a chemical change to iron oxide, which is responsible for rusting.
How does living near the sea contribute to rusting?
Near the sea exposed metals have a greater exposure to salts, which accelerate the rusting process.
What is a major cause of rancidity of lipids in foods is exposure to?
Rancidity is caused by hydrolysis and oxidation. Heat, moisture and exposure to light will increase these chemical reactions and thus increase the likelikhood of the onset of rancidity.
Why is wearing lewellery not recommcnded in the kitchen?
The precious metals being soft excepting platinum,would be eroded due to its exposure to physical wear and tare.
Which group of elements are very reactive with water?
The column you're looking for is called the Alkali metals. They are very reactive, but not JUST with water. They actually violently react with almost ANYTHING if they aren't already with another element. Exposure to air, skin, dirt, other metals, It all ends with violence (i.e. huge explosions).
What are the ways wharein fat deteriorate?
Fats deteriorate upon exposure to oxygen, heat, metals, and light. A lot depends on what sort of fat it is. Animal fats are more susceptible to damage from oxygen and metals. Vegetable fats are more susceptible to damage from heat and light.
