Carbon's atomic number is 6; therefore, any neutral isotope of Carbon will always have exactly 6 electrons: stable neutrons have nothing to do with the electron count of an atom.
32 protons, 32 electrons. Ge-72 isotope has 40 neutrons
For the isotope carbon-12: 6 protons, 6 neutrons, 6 electrons
Silicon-29 has 14 protons and 15 neutrons. Since atoms are electrically neutral, it will also have 14 electrons.
In a neutral atom, there will be the same number of electrons as protons, with the number of protons being the same as the atomic number, 29. The number of neutrons it has depends on the specific isotope; however, the most common naturally occurring isotope is 63Cu, with 34 neutrons. See link below.
A neutral atom of sodium has 11 electrons. Sodium-25 refers to the isotope of sodium with 25 total protons and neutrons, so a neutral sodium-25 atom would still have 11 electrons to balance the 11 protons in the nucleus.
The most important isotope of beryllium - 9Be - has 5 neutrons. The neutral atom of beryllium has 4 electrons.
32 protons, 32 electrons. Ge-72 isotope has 40 neutrons
38 protons. If it is neutral, it will also have 38 electrons. The number of neutrons obviously varies, depending on the isotope.
Number of neutrons = Atomic mass of an isotope - Atomic number of the element The atomic number of meitnerium is 109. Each isotope of an element has a different number of neutrons.
For the isotope carbon-12: 6 protons, 6 neutrons, 6 electrons
The aluminum atom has 13 electrons and protons and also 14 neutrons.
Silicon-29 has 14 protons and 15 neutrons. Since atoms are electrically neutral, it will also have 14 electrons.
In a neutral atom, there will be the same number of electrons as protons, with the number of protons being the same as the atomic number, 29. The number of neutrons it has depends on the specific isotope; however, the most common naturally occurring isotope is 63Cu, with 34 neutrons. See link below.
Sodium's atomic number is 11. Thus, neutral sodium has 11 protons and 11 electrons per atom. 23Na is sodium's only stable isotope, having 23 - 11 = 12 neutrons.
The atomic number of phosphorus is 15. Thus, neutral phosphorus will have 15 protons and 15 electrons. The only stable isotope of phosphorus is 31P, meaning it has 31 - 15 = 16 neutrons.
Curium has 96 electrons in the neutral state. Number of neutrons = Atomic mass of an isotope - atomic number of the isotope The atomic number of curium is 96; for the isotopic masses of curium read at the link below.
He-4 isotope has 2 neutrons.
