When a structural formula of a molecule shows a single line between two atom symbols such as $\mathrm{H}-\mathrm{H}$, that means
the 2 atoms are sharing a pair of electrons
the 2 atoms are sharing one electron
one atom has given one electron to the other atom
the 2 atoms are sharing 2 electrons
the 2 atoms are sharing 2 pairs of electrons
Solution
Solution Steps
Step 1: Identify the Meaning of a Single Line in Structural Formulas
A single line between two atom symbols in a structural formula represents a single covalent bond.
Step 2: Understand Covalent Bonds
In a single covalent bond, two atoms share a pair of electrons.
Step 3: Match the Correct Option
The correct interpretation is that the two atoms are sharing a pair of electrons.
Step 4: Conclusion
The correct answer is: the 2 atoms are sharing a pair of electrons.
