12
A stable magnesium atom has 12, 13 or 14 neutrons. The atom with 12 neutrons is the most common one.
Silicon has 14 protons, so it typically has 14 neutrons as well to maintain a stable atomic structure.
94 protons, 94 electrons, and 150 neutrons
41 protons 41 electrons 52 neutrons
In europium, the number of protons is 63, electrons is also 63, and neutrons can vary based on the isotope of europium. The most common isotope, europium-153, has 90 neutrons.
146 neutrons.
In the most common isotope of silicon, there are 14 neutrons.
6 protons. The number of neutrons varies, but the most common isotope has 6 neutrons.
The most common isotope of Neon has 10 neutrons.
Boron has 5 neutrons and 5 protons for its most common isotope
nm
Boron has 5 neutrons and 5 protons for its most common isotope
The atomic mass of Lithium is 6.941. Its has 3 protons and the most common has 4 neutrons.
Lol kryplon. If you meant krypton, the most common (as well as stable) isotope has 48 neutrons.
A stable magnesium atom has 12, 13 or 14 neutrons. The atom with 12 neutrons is the most common one.
Eleven. This because sodium has an atomic number (also the number of protons) of 11 on the periodic table. All the elements listed on the table are the most common (or only) isotopes of those elements.
Barium has 81 neutrons :D
