Verified step by step guidance1
Understand the nature of a covalent bond: A covalent bond is a type of chemical bond where two atoms share one or more pairs of valence electrons.
Differentiate between covalent and ionic bonds: In ionic bonds, electrons are transferred from one atom to another, resulting in the formation of ions. In covalent bonds, electrons are shared between atoms.
Identify the key requirement for covalent bond formation: For a covalent bond to form, the involved atoms must share electrons to achieve a more stable electron configuration.
Consider the options given: Analyze each option to determine which one describes the sharing of electrons. The correct option should indicate that electrons are shared, not transferred, lost, or gained.
Conclude with the correct understanding: The correct statement for the formation of a covalent bond is that the atoms must share electrons, as this sharing allows them to achieve a stable electron configuration similar to that of noble gases.
