2\. Above the symbol is the atomic number (Z) which is equal to the number of protons in the nucleus and the number of electrons in the electron cloud (given that the atom is neutral). For carbon Z=6. 3\. Below the symbol is the atomic mass. While this number is a weighted aver...
If you know the atomic number and the mass number of an isotope of an element, how can you determine the number of protons and neutrons? For atomic s states, the probability density |\psi |^2 is the largest at the origin, yet the probability of finding the electron at a distance r ...
If you know the atomic number and the mass number of an isotope of an element, how can you determine the number of protons and neutrons?Answer and Explanation: The atomic number is equal to the number of protons in an atom. For ...

How could you determine the number of neutrons in a carbon 14 atom? How many total number of neutron are present ? Determine the mass number of a beryllium atom with 5 neutrons. How does one isotope differ from another? How to calculate protons, neutrons and electrons ...
It's not that simple though. An atom's properties can change considerably based on how many of each particle it has. If you change the number of protons, you wind up with a different element altogether. If you alter the number of neutrons in an atom, you wind up with an isotope. For...
Each atom contains three small subatomic particles -- protons, neutrons, and electrons. In the center of the atom, the protons and neutrons gather to form the nucleus, while the electrons zip around that nucleus as if they are minute planets orbiting their own little sun [source: Northwestern...
