We’re being asked to determine which of the following elements canform compounds with an expanded octet.
Recall that the octet rule states that an element is surrounded by eight electrons in the Lewis structure.
Exceptions to this rule occur when:
• there is an odd number of electrons, like in radicals
• there are less than 8 electrons or incomplete octet
• there are more than 8 electrons or expanded octet. This occurs to nonmetals from Period 3 to 7.
Which of the following elements can form compounds with an expanded octet?
e. None of the above
