Atomic hydrogen is very reactive. It combines with most elements to form hydrides (e.g., sodium hydride, NaH), and it reduces metallic oxides, a reaction that produces the metal in its elemental state. … Almost all metals and nonmetals react with hydrogen at high temperatures.
What is hydrogens reactivity?
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.
What is the order of reactivity of hydrogen atom?
1o>2o>3o.
Why is hydrogen gas not reactive?
H2 is unreactive compared to diatomic elements such as halogens or oxygen. The thermodynamic basis of this low reactivity is the very strong H-H bond, with a bond dissociation energy of 435.7 kJ/mol. The kinetic basis of the low reactivity is the nonpolar nature of H2 and its weak polarizability.
Which is more reactive hydrogen or oxygen?
Hydrogen is more reactive than oxygen because the outermost shell of H have 1 electron and needs one more to complete its octet whereas O have 4 electrons in its valance shell and needs 5 more electrons to complete its octet.
Which is more reactive molecular hydrogen or nascent hydrogen Why?
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.
Why is hydrogen 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.
Is hydrogen 3 stable or unstable?
