U-238 (Uranium-238) has 92 Electrons
Isotope U-238 has 92 electrons. This number corresponds to the atomic number of uranium, which is 92.
Hafnium has 72 electrons and protons; the number of neutrons is different for each isotope and depend on atomic mass of the isotope.
All neutral sodium atoms have 11 electrons, regardless of the isotope.
Isotope Ni-63 has 28 electrons (it is found by looking at the atomic number for Nickel on the periodic table) and has 35 neutrons (which is found by subtracting the number in the isotope, 63, by the atomic number, 28)
Sulfur-34 has 16 electrons, as the number of electrons in an atom is equal to the number of protons, which in the case of sulfur is 16.
Nickel (Ni) has 28 protons and 28 electrons. Its most common isotope, Nickel-58, has 30 neutrons.
Every isotope of magnesium has 12 electrons.
If 42 is the atomic number then there is 42 electrons in isotope.
The isotope Cr-54 has 24 electrons.
92
Every isotope of cobalt has 27 electrons.
Seven.
Hafnium has 72 electrons and protons; the number of neutrons is different for each isotope and depend on atomic mass of the isotope.
Silicon has 14 electrons. The atomic number of silicon is 14, which corresponds to the number of protons and electrons in a neutral silicon atom.
This question is impossible to answer properly without knowing either how many protons there are or how many neutrons there are or how many electrons there are along with the charge. However it is most likely nitrogen, because Nitrogen's most common isotope is 14.
Protactinium has 91 protons and electrons; the number of neutrons is different for each isotope: Number of neutrons = Atomic Mass of the isotope - 91
Radium has 88 electrons. The number of neutrons is different for each isotope: Number of neutrons = Atomic mass of an isotope - 88
The isotope 210Rn has 86 protons and electrons; also 124 neutrons.
