If you were to look at a periodic table, you'd see that potassium (K) has an atomic number of 19, which is how many protons it has. Also because it's neutral, the number of protons = the number of electrons, but only protons and neutrons are inside the nucleus.

Answer:
The correct option is number 3. A deficit of appositional bone growth would not be life threatening.
Explanation:
Appositional bone growth can be defined as the thickening of the bones due to increase in the number of bone tissues at the surface. In this kind of bone growth, the diameter of the bone increases rather than the length of the bone. This can lead to deformation of the bone but it is not life-threatening.
Rest of the options 1, 2 and 3 are serious disorders and can eventually lead to death.
