Why is hydrogen so reactive?
It includes the nonmetal hydrogen (H) and six metals that are called alkali metals. Elements in the same group of the periodic table have the same number of valence electrons. All the elements in group 1 have just one valence electron. This makes them very reactive.
Which hydrogen is more reactive?
nascent hydrogen
The production of nascent hydrogen is associated with the release of high energy. This released energy activates the nascent hydrogen and makes it more energy rich than that of ordinary occurring molecular hydrogen. Because more energy means more reactivity, nascent hydrogen is more reactive than molecular hydrogen.
Is hydrogen reactive and unstable?
Hydrogen only has one electron in its lowest energy level. This is a very unstable arrangement, and hydrogen gas undergoes a variety of reactions so as to reach a stable electron configuration where its energy level is either empty of electrons, or filled with electrons.
Is hydrogen reactive with oxygen?
Hydrogen is a highly reactive fuel. Hydrogen molecules violently react with oxygen when the existing molecular bonds break and new bonds are formed between oxygen and hydrogen atoms. But hydrogen does not react with oxygen at room temperature, a source of energy is needed to ignite the mixture.
Is hydrogen reactive with water?
Hydrogen does not react with water. It does, however, dissolve to the extent of about 0.00160 g kg-1 at 20°C (297 K) and 1 atmosphere pressure.

What is significant about Chnops?
The acronym CHNOPS, which stands for carbon, hydrogen, nitrogen, oxygen, phosphorus, sulfur, represents the six most important chemical elements whose covalent combinations make up most biological molecules on Earth. All of these elements are nonmetals.
What is the most reactive metal than hydrogen?
This shows magnesium is more reactive than zinc and both metals are more reactive than hydrogen. This third displacement reaction can be used for any metal that appears lower than itself on the table. The further apart the two metals appear, the more vigorous the reaction.
Why is nascent hydrogen more reactive than molecular hydrogen?
Because more energy means more reactivity, nascent hydrogen is more reactive than molecular hydrogen. The second reason for higher reactivity of nascent hydrogen is related with the high internal pressure.
Why is hydrogen located in group with reactive metals?
Hydrogen is included in the reactivity series of metals because it’s property of electroposivity (i.e losing electron to form positive ion) is similar to that of metals, thats why we can relate it with metals.
Why are hydrogen ions so reactive?
Atomic hydrogen is so reactive because it has one electron in its orbit that can contain two electrons – so it can either donate that electron or accept an electron from another atom. Molecular hydrogen is stable because two hydrogen atoms share their electrons to have a full valence shell.
