Why would hydrogen exist as a molecule?

Answer 1

Hydrogen exists as a molecule (H2) because each hydrogen atom has one electron in its outer shell, and by sharing electrons with another hydrogen atom, they can achieve a stable electron configuration similar to helium. This sharing of electrons forms a covalent bond between the two hydrogen atoms, creating a more stable molecule than individual atoms. Additionally, the bond between the two hydrogen atoms releases energy, making the H2 molecule more stable than separate hydrogen atoms.

Answer 2

Hydrogen exists as a molecule because it is a diatomic element. In its elemental form, hydrogen exists as H2 molecules, where two hydrogen atoms are bonded together by a covalent bond to achieve stability. This molecular form is the most stable and common form of hydrogen under standard conditions.

Answer 3

There are three sets of interactions in this system: The 4th explains: Why? # Repulsion between the two electrons (one interaction of this type) # Repulsion between the two nuclei (one interaction of this type) # Attractions between each electron and nucleus (four separate interactions of this type # Therefore a single hydrogen atom is less stable and requires less energy to break down.

Answer 4

Each individual hydrogen atom has one electron. Atoms always want to be in the lowest energy state possible therefore the hydrogen atoms will combine to fill the 1s orbital by sharing the two electrons in a covalent bond. This fills hydrogen's so called "octet".

Answer 5

All the elements of the periodis table try to attain noble gas stable electronic configueation.A monoatomic hydrogen atom, containing 1 electron in its orbit or valence shell,

is highly unstable.

So inorder to complete its duplate it forms a covalent bond i.e is it shares an electron with another monoatomic hydrogen atom and forms diatomic hydrogen atom.

Thus,it attains noble gas stable electronic configuration and becomes stable.

Answer 6

Two hydrogen atoms will form covalent bond by sharing the one and only electron that each of them have . Each hydrogen now theoretically has two electrons in its first(or s) shell and they have a electronic configuration of Helium atom, which is inert and stable. Therefore, hydrogen exists in a form of H2.

Answer 7

hydrogen exist in nature as a molecule of two atoms rather than as separate atoms because one hydrogen atom is unstable

Answer 8

hydrogen exist in nature as a molecule of two atoms rather than as separate atoms because one hydrogen atom is unstable

Answer 9

because its highly reactive and will react with itself to form H2

Answer 10

Hydrogen atoms need one electron in order to fill their valence shell. They do this primarily by forming covalent bonds with other atoms.
