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.
15 protons, 15 electrons and 16 neutrons (for its most stable isotope)
For the isotope carbon-12: 6 protons, 6 neutrons, 6 electrons
Polonium has 84 protons and electrons; the number of neutrons is different for each isotope: Number of neutrons = Atomic mass of an isotope - Atomic number of polonium (84)
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.
26 electron, the atomic number of the element in the periodic table tells us the number of electron in the neutral atom.
The most important isotope of beryllium - 9Be - has 5 neutrons. The neutral atom of beryllium has 4 electrons.
15 protons, 15 electrons and 16 neutrons (for its most stable isotope)
For the isotope carbon-12: 6 protons, 6 neutrons, 6 electrons
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.
The aluminum atom has 13 electrons and protons and also 14 neutrons.
It contains 104 electrons/protons and 159 neutrons.
Polonium has 84 protons and electrons; the number of neutrons is different for each isotope: Number of neutrons = Atomic mass of an isotope - Atomic number of polonium (84)
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.
Radium has 88 electrons. The number of neutrons is different for each isotope: Number of neutrons = Atomic mass of an isotope - 88
O-18 atom has 8 protons, 8 electrons and 10 neutrons.
He-4 isotope has 2 neutrons.
