Question

think it over 4. apply study the oxygen atom illustrated below. is the second energy level of the oxygen atom full? explain. nucleus 8 protons (p⁺) 8 neutrons (n⁰) 8 electrons (e⁻) oxygen atom

Explanation:

Step1: Recall electron - shell capacity

The first energy level can hold a maximum of 2 electrons. The second energy level can hold a maximum of 8 electrons.

Step2: Analyze oxygen's electron distribution

Oxygen has 8 electrons. The first energy level has 2 electrons. So the number of electrons in the second energy level is \(8 - 2=6\) electrons.

Answer:

No, the second energy level of the oxygen atom is not full. The second energy level can hold a maximum of 8 electrons, but the oxygen atom has only 6 electrons in its second energy level.
