Question

1. predict: each hydrogen atom has one valence electron, but it needs two electrons to be stable. how can both hydrogen atoms each achieve a stable configuration?
2. form a bond: drag the electrons so that they move around both hydrogen atoms. click play to observe them in orbit, and then click check. you have created a covalent bond.

congratulations, you have completed a molecule of hydrogen! because the molecule has two atoms, it is a diatomic molecule. click the camera ( ) icon to take a snapshot of your completed molecule. right - click the image, and click copy image. paste the image into the document below and label the image “h₂.”

1. draw a diagram: covalent bonds are shown in lewis diagrams. in a lewis diagram, dots represent unshared valence electrons and dashes represent pairs of shared electrons.

turn on show lewis diagram. what is the lewis diagram for hydrogen, h₂? h h

Explanation:

1. Two hydrogen atoms can share their single - valence electrons to form a covalent bond, achieving a stable duet configuration.
2. A covalent bond is formed by sharing electrons between atoms. In hydrogen, two hydrogen atoms share their electrons to form a diatomic molecule ($H_2$).
3. In the Lewis diagram for $H_2$, since each hydrogen atom contributes one electron and they share these two electrons in a covalent bond, the Lewis diagram is $H:H$ (where the colon represents the shared pair of electrons).

Answer:

1. By sharing their valence electrons to form a covalent bond.
2. A covalent bond is formed by sharing electrons between the two hydrogen atoms to create a diatomic molecule of hydrogen ($H_2$).
3. $H:H$
