Look at the Periodic Table. You see that the element that has 16 protons is Sulfur.
Electrons have a single negative charge, while protons have a single positive charge, so an ion with 2 more electrons than protons will have a charge of 2-.
So, the symbol of the ion would be S2- .
A sulfide ion has 16 protons and 18 electrons. The -2 charge indicates that the ion has gained two electrons, giving it two more electrons than protons.
The ion S(2-) has 16 protons and 18 electrons.
A phosphorus atoms has 15 protons and will form an ion with 18 electrons. Phosphorus-31 is one of the isotopes.
P3- has 15 protons, 16 neutrons and 18 electrons.
A Sulfide ion has a full complement of 8 valence electrons. Sulfur is element 16. It has 6 valence electrons in its outer energy level, however, sufide is S2- so it has gained 2 electrons to fill its outer energy level.
S for sulfur because the number of protons tells you the atomic number with is 16 and 16 is sulfur. The electrons means it is an ion with two more electrons than protons. The neutrons have no charge but add mass to the element.
In a sulfur ion with a charge of 2-, there are 18 electrons (16 from the neutral sulfur atom and two additional electrons to account for the negative charge). The number of protons remains the same as in a neutral sulfur atom, which is 16.
A sulfide ion has 16 protons and 18 electrons. The -2 charge indicates that the ion has gained two electrons, giving it two more electrons than protons.
The sulfide ion (S²⁻) has 16 protons and 18 electrons. This is because the element sulfur (S) normally has 16 protons and 16 electrons, but by gaining two extra electrons to achieve a stable electron configuration, it becomes the sulfide ion with 18 electrons.
A sulfide ion has 16 protons and 18 electrons. The additional electron gives the ion a negative charge, making the number of electrons greater than the number of protons.
A sulfide ion (S2-) has 16 protons. This is because the sulfide ion carries a charge of -2, indicating that it has gained two extra electrons, and thus has 16 protons in its nucleus as the number of protons always determines the element.
16 protons and 18 electrons
The ion S(2-) has 16 protons and 18 electrons.
i think it depends how many electrons it has. then you do something like subtract the electrons from the protons. electrons are negative, protons are positive.
A phosphorus atoms has 15 protons and will form an ion with 18 electrons. Phosphorus-31 is one of the isotopes.
p=16 e=16 if it is not an ion n=16
Sulfur is a chemical element with the symbol S and atomic number 16. It has 16 protons, 16 neutrons and 16 electrons.
