Water that is in the form of clouds is relatively pure, although it does contain some dissolved pollutants from the air. Probably the purest you could find is old glacial ice in Antarctica, deposited at a time when global air pollution levels were much lower.
Sodium is a highly reactive element and is typically found in nature combined with other elements such as chlorine in salt deposits or in compounds like sodium hydroxide. It is rarely found in its pure form because it readily reacts with air and water.
Pure iron is rarely found in its pure form in nature because it readily reacts with oxygen to form iron oxide (rust). However, iron can be purified through industrial processes to obtain pure iron for various applications.
Calcium is rarely found in its pure form in nature because it readily reacts with other elements to form compounds. It is most commonly found in the form of calcium carbonate in minerals such as limestone and marble.
Zinc is usually combined with other elements.
Chlorine is a diatomic gas at room temperature, typically found as Cl2 molecules. It is a highly reactive element and is rarely found in its pure form in nature.

Hydrogen is found in nature primarily as a compound, such as in water (H2O) or hydrocarbons. Pure elemental hydrogen is rare in nature but can be found in some volcanic gases or certain chemical reactions.

No, water found in nature is not always pure. It can be contaminated by pollutants, chemicals, bacteria, and other impurities, making it unsafe for consumption without purification. It's important to treat natural water sources before drinking them to ensure they are safe for consumption.
Alkali metals are not found as pure elements in nature.
Chlorine is a diatomic gas at room temperature, typically found as Cl2 molecules. It is a highly reactive element and is rarely found in its pure form in nature.
Lead is rarely found in its pure form in nature. It is typically found in combination with other elements, such as lead sulfide (galena) or lead carbonate. Lead ore must be processed to extract the lead metal from these compounds.
They are highly reactive.
Chlorine gas is the product of some chemical reactions, but the pure element is EXTREMELY reactive and is rarely found in nature.Chlorine is common in compounds such as sodium chloride (ordinary table salt).
The Group 1 elements, the alkali metals, are so reactive that they have to be stored in oil; they will react explosively with water and since water is so prevalent in nature and the alkali metals are so unstable, you'd be very hard-pressed to find a naturally occurring sample. I urge you to go on youtube and look up reactions of Group 1 metals reacting with water. It's quite amusing.
