Question

onding
atoms can achieve a full
outer shell of electrons
either by transferring
electrons or by sharing
electrons with other atoms.
this results in the formation
of chemical bonds.

click on the hotspots to
compare the chemical bonds
formed by lithium and
fluorine with that of a
hydrogen molecule.

hydrogen (h)
hydrogen molecule (h₂)

Explanation:

Since the problem seems to be about chemical bonding (related to how atoms form bonds, like in the hydrogen molecule and comparing with lithium - fluorine bonding), and there's no specific question asked (like explaining the bonding, identifying the type, etc.), we can't provide a proper solution. If you want to know about the type of bonding in hydrogen molecule (covalent, as they share electrons) or the bonding between lithium and fluorine (ionic, as lithium transfers an electron to fluorine), or any other aspect, please clarify the question. For now, based on the given content, if we assume the question is about the type of bonding in $H_2$:

In a hydrogen molecule ($H_2$), two hydrogen atoms each have 1 electron in their outer shell. To achieve a full outer shell (like helium with 2 electrons in the first shell), they share their electrons. This type of bonding where atoms share electrons is called covalent bonding.

Answer:

The hydrogen molecule ($H_2$) forms a covalent bond by sharing electrons between the two hydrogen atoms.
