please review information in modules 1a and 1c before attempting the assign for each attempt. this knowledge check may cover material that has not been covered in lectu required reading. assignments submitted after the due date earn zero points. question 1 a covalent bond is formed when two atoms gain and lose electrons. share an electron with each other. gain electrons. share one or more pairs of electrons with each other.

Explanation:

To determine the correct answer, recall the definition of a covalent bond. A covalent bond involves atoms sharing one or more pairs of electrons.

• "Gain and lose electrons" describes ionic bonding (transfer of electrons).
• "Share an electron with each other" is incorrect; covalent bonds involve sharing pairs (not single electrons in this simplistic way).
• "Gain electrons" is not specific to covalent bonding (e.g., some atoms gain electrons in ionic bonds too).
• "Share one or more pairs of electrons with each other" matches the covalent bond definition.

Answer:

D. share one or more pairs of electrons with each other. (Assuming the last option is labeled D; if the original options had labels like A, B, C, D with the last being D, else adjust the label. From the image, the last option is "share one or more pairs of electrons with each other" which is the correct one.)
