Question

Which of the following statements correctly describes energy levels

In its outermost energy level, oxygen has 4 valence electrons.
B. Electrons can never move to a higher or lower energy level.
C. The second energy level holds a maximum of four electrons.
D. The greater the energy of the level, the farther away it is from the nucleus.

Answer 1

-In Outermost energy level, Oxygen has 6 valence electrons.
-Electrons can move to Higher as well as to lower energy level.
-The second energy level holds a maximum of eight electrons.

In short, Your Answer would be: Option D) The greater the energy of the level, the farther away it is from the nucleus

Hope this helps!

Answer 2

D) The greater the energy of the level, the farther away it is from the nucleus

Step-by-step explanation:

• Oxygen's valence shell has 6 electrons.
• Provided the right amount of energy electrons can move to higher energy level and by emiting energy it can move to a lowe energy level.
• The second energy level holds a maximum of eight electrons (2 s2 3p6). A table with such values is attached.
• The greater the energy of the level, the farther away it is from the nucleus, a graph with orbital as fucntion of energy is attached.
