It's better than 7
The second energy level can hold a maximum of 8 electrons. Magnesium has 12 electrons, so in its second energy level, there will be 8 electrons (2 in the first energy level and 8 in the second energy level).
Potassium has four(4) energy levels.

Oxygen has 8 protons.
The element with 3 energy levels and 8 neutrons in its outer energy level is oxygen, with the symbol O. Oxygen has 8 protons and 8 neutrons in its nucleus, with 2 electrons in its inner energy level and 6 electrons in its outer energy level.

A hemoglobin level of 4.7 is dangerously low and if not properly treated could become fatal. Normally, women should have a hemoglobin level of 12 or more, men 13 or more. Generally, hospitals will begin emergency blood transfusions when the hemoglobin level drops below 7 or 8.

If your hemoglobin level is low, you need to do something about it. The question is how low? If it is below 8, you may need a blood transfusion. If it is above that, you need to start eating red meat, green vegetables, and taking an iron supplement.

Gastly should learn mean look at level 8 :)
Well it is certainly not good! Normal hemoglobin values range from 12-16 for females and from 14-18 for males. My husband just had a gastrointestinal bleed, and when his hemoglobin level dipped below 9, they transfused him. His original level upon admittance was 5.8, and he had 8 units of blood before they could get him up above the "9" that they required before they would let him go home. So...you need some iron! I'd def. call the doc about this one...not anything to play around with.
