A sulfide ion (S²⁻) is derived from a sulfur atom that has gained two electrons. A neutral sulfur atom has 16 protons and 16 electrons. However, the sulfide ion has 16 protons and 18 electrons due to the additional two electrons it gains to achieve a -2 charge.
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.
16 protons and 18 electrons
it has 2 more electrons than protons.
No. By definition an ion is electrically charged and so must have a different number of protons and electrons. A chloride ion has 17 protons and 18 electrons.
An ion that has more electrons than protons has a negative charge.
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.
16 protons and 18 electrons
The number of protons of an element does not change when it undergoes a chemical change. It is the number of electrons that changes. Sulfur has 16 protons, and so does the sulfide ion. However, sulfur has 16 electrons, while the sulfide ion (S2-) has 18 electrons.
it has 2 more electrons than protons.
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.
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.
Sulpher atom has an atomic no. of 16 and a mass no. of 32 neutrons = mass no. - atomic no. = 32 - 16 = 16 when an atom becomes an ion only theelectron no. changes while the proton and neutron no. stays the same. the neutron no. changes in isotopes only!!!
When calcium gives away 2 electrons, it becomes positively charged have 2 more protons than electrons. So it is Ca2+ ion. Sulfur gaining 2 electrons contains 2 more electrons than protons. So it becomes S2- ion. The compound formed isCalcium Sulfide = Ca2+S2- = CaS
The Sulfide ion, S2-, is isoelectronic with Cl-
A sulfur atom gains 2 electrons when it becomes a sulfide ion.
