The same as any other isotope of carbon: four.
A carbon-12 atom has 6 electrons. The atomic number of carbon is 6, which determines the number of electrons in a neutral carbon atom.
6
there are 12 electrons in carbon. you can find this out by looking at the "ATOMIC NUMBER"
6 protons, 6 electrons and 6 protons in carbon-12 atom
2 electrons orbit in the outer shell. If its a neutral atom, then it will have the same number of electrons as protons. Magnesium has 12 protons and 12 electrons.
In all there are 6 electrons, but the electrons are distributed over 2 shells. In the first shell, there are 2 electrons, and in the second there are 4 electrons. Note that this applies to the neutral atom of carbon.
2 electrons orbit in the outer shell. If its a neutral atom, then it will have the same number of electrons as protons. Magnesium has 12 protons and 12 electrons.
Magnesium has a total of 12 electrons. The electron configuration would be 1s2 2s2 2p6 3s2. Therefore, 2 electrons in it's outer shell.
Carbon-13 has 6 protons and 7 neutrons, making a total of 13 particles in its nucleus. Since atoms are electrically neutral, it also has 6 electrons to balance the charge of the 6 protons.
12
Niobium has 5 electrons in its outer shell. It belongs to group 5 in the periodic table, which means it has 5 valence electrons.
c=4 valence electrons S=6 valence electrons but since its S2 you times 6 by 2=12 12+4=16 16 valence electrons total for CS2
