16 protons and 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.
All lithium atoms and ions have three protons. The lithium ion has a charge of +1, meaning there is one less electron than protons, two.
it has 2 more electrons than protons.
chloride ion is formed when chlorine atom adds one electron. Chloride ion thus has 17 protons and 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.
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.
There are 16 protons in the sulfide ion, which is similar to the sulfur atom.
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.
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.

All lithium atoms and ions have three protons. The lithium ion has a charge of +1, meaning there is one less electron than protons, two.
There are 19 protons in an ion with 18 electrons and a -1 charge. The -1 charge indicates that the ion has gained an extra electron, resulting in one more electron than protons.
it has 2 more electrons than protons.
An ion is defined as an element with a charge. Because elements vary with how many protons they have (along with neutrons to form isotopes) it is impossible to put a set number on how many protons and electrons all ions have. An element (or compound) becomes an ion when the substance gains (to become a positive ion) or loses (to become a negative ion) an electron(s).
chloride ion is formed when chlorine atom adds one electron. Chloride ion thus has 17 protons and 18 electrons.
A fluorine ion with a charge of 1 indicates that it has gained an extra electron, making it a fluoride ion. So, a fluoride ion would have 10 electrons (9 from the protons and 1 extra electron).
