The atomic number of an element is the same as the number of protons. In a neutral atom, the number of electrons is the same as the number of protons. The average mass for each element is the weighted average of that element’s naturally occurring isotopes. calculate relative atomic mass;

Atomic number of an element is the number of protons in 1 atom of that element. Since an oxygen atom has 8 protons, the atomic number of the element oxygen (O) is 8 .
If we now take the transport of Pi into consideration, it takes 4 protons to synthesize 1 ATP molecule. We divide the total number of protons from NADH (100) and FADH2 (12) (=112) to get 28 ATP produced. When we add the 4 ATP produced as a result of glycolysis and TCA, we get 32 ATP produced per molecule of glucose.
The atomic number is the number of protons. That is, the number of protons in the potassium (K) is 19. Electrons equal to protons are located in a circular shell (orbit) outside the nucleus. That is, the potassium (K) atom has a total of nineteen electrons.
An atom has an atomic number of 9 and a mass number of 19. Solution: There are 9 protons because the atomic number is always equal to the number of protons present. There are 10 neutrons because the number of neutrons is always obtained by subtracting the atomic number from the mass number.
There are nine protons in an ion with 10 electrons and a -1 charge. Likewise, how many protons does an ion with 10 electrons and a charge of +2 contain? O2- indicates an ion of oxygen having two extra electrons.
