Give the number of electrons in the species, O2 and O2+.
Understand the Problem
The question asks for the number of electrons present in O2 and O2+. This requires understanding the electronic structure of oxygen and how ionization affects the number of electrons.
Answer
The answer is (d) 16 and 15
The number of electrons in O2 is 16, and the number of electrons in O2+ is 15. Therefore, the answer is (d) 16 and 15.
Answer for screen readers
The number of electrons in O2 is 16, and the number of electrons in O2+ is 15. Therefore, the answer is (d) 16 and 15.
More Information
An oxygen atom has 8 electrons. O2 has two oxygen atoms, so it has 16 electrons. O2+ has one less electron than O2 because it has a positive charge. Therefore O2+ has 15 electrons.
Tips
A positive charge indicates the loss of electrons, while a negative charge indicates the gain of electrons.
