WebMany elements—such as carbon, potassium, and uranium—have multiple naturally occurring isotopes. A neutral atom of Carbon-12 contains six protons, six neutrons, and six electrons; therefore, it has a mass number of 12 (six protons plus six neutrons). Web26 nov. 2024 · It is interesting to note that the extent to which Complex IV’s content and activity are reduced in mitochondria from L 186 P, H 114 Q yeast (65% vs WT) is much less important than the drop in the rate of ATP synthesis (20% vs WT), which further indicates there is still in this mutant a quite good flow of protons through the F O despite its poor …

Complete the following questions concerning the element oxygen: a. Number of protons b. WebPotassium-41 - It has 19 protons and atomic mass is 41. Hence, number of neutrons is 41 - 19 which is 22. Hence, the Potassium number of neutrons are 20, 21 and 22. I … Therefore, a potassium atom has nineteen protons and nineteen electrons. The number of neutrons in an atom can be determined by the difference between the atomic mass and the number of protons. The difference between the mass number of the potassium atom and the number of protons is twenty.
