is hydrogen uncombined in nature
They are very reactive.They cannot be found uncombined.
Alkali metals are very reactive and tend to form compounds with other elements. They are not found in their pure form in nature due to their high reactivity with moisture and air. Instead, they are typically found combined with other elements in minerals such as silicates, carbonates, and chlorides.
Yes
Yes, have you ever found spider eggs on a leaf while exploring nature?
Yes In high temperature gas cooled nuclear fission reactors using the nuclear process heat.
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.
All the chemical elements from group I and II are very reactive; it is impossible to found these elements in nature in elemental state.
Henry Cavendish, a young English chemist, discovered that hydrogen is a separate substance in 1766. It was also discovered that hydrogen is found naturally in the atmosphere, and when hydrogen is burned it produces water vapor
The 50 Megaton "Tsar Bomba" hydrogen bomb tested by the USSR in 1961 is the strongest hydrogen bomb ever detonated. The 10 Megaton "Ivy Mike" hydrogen bomb tested by the U.S. in 1952 is the physically largest hydrogen bomb ever detonated.
it is is one of the property of hydrogen as it is highly inflammable gas ever known . it is also used in hydrogen bombs.
Vampires are fictional. No vampire has ever been found.
who are you have you ever looked at the periodic table of elements? Hydrogen is the lightest element while helium is the second lightest element. No.
