Question

question 7
the chemical symbol o=o means ______.
this is an ionic bond with two shared electrons
zero equals zero
both atoms are bonded and have zero electrons in the outer orbit
the atoms are double bonded
clear selection

Explanation:

• Analyze each option:
• "this is an ionic bond with two shared electrons": Ionic bonds involve transfer, not sharing, and O=O is covalent, so this is wrong.
• "zero equals zero": This is a mathematical interpretation, irrelevant to chemical bonding, so wrong.
• "both atoms are bonded and have zero electrons in the outer orbit": Oxygen has electrons in outer orbit (valence electrons), so this is wrong.
• "the atoms are double bonded": In chemical notation, "=" represents a double covalent bond, so O=O means two oxygen atoms are double - bonded.

Answer:

D. the atoms are double bonded (assuming the last option is labeled D; if the original options had labels like A - D, with the last option being the correct one, the answer is the option stating "the atoms are double bonded")
