Q. What is the number of electrons in S2 -?
18 electrons
Q. How many protons and electrons are in sulfide ion?

Q. What is the electron configuration for the sulfide anion S2 -?
S: 1s2 2s2 2p6 3s2 3p4 S2- : 1s2 2s2 2p6 3s2 3p6 Note: Replacement of 1s2 2s2 2p6 by [Ne] is acceptable.
Q. What ion is formed by sulfur?
Sulfide
Q. What charge does sulfur ion have?
1.17: Ions
| Element | Protons | Net Charge |
|---|---|---|
| Potassium atom | 19 | 0 |
| Potassium ion | 19 | +1 |
| Sulfur atom | 16 | 0 |
| Sulfur ion | 16 | −2 |
Q. What happens when a sulfur atom becomes an ion?
Main group metals retain their name when forming cations. However, when non-metallic elements gain electrons to form anions, the end of their name is changed to “-ide.” For example, a fluorine atom gains one electron to become a fluoride ion (F-), and sulfur gains two electrons to become a sulfide ion (S2-).
Q. Is the charge of sulfur?
https://www.thoughtco.com/element-charges-chart-603986 (accessed June 23, 2021)….Table of Common Element Charges.
| Number | Element | Charge |
|---|---|---|
| 16 | sulfur | 2-, 2+, 4+, 6+ |
| 17 | chlorine | 1- |
| 18 | argon | 0 |
| 19 | potassium | 1+ |
Q. How will Sulfur become an ion?
When forming an ionic compound with one atom of sulfur, two potassium atoms are used. Each potassium atom donates its outermost electron to the sulfur atom, forming ions with a 1+ charge, due to the loss of an electron. When sulfur receives these two electrons, it is ionised itself, becoming an ion with a 2- charge.
Q. Is Potassium a sulfur?
Potassium sulfide represented by the chemical formula K2S is a compound of potassium and sulfur that is moderately soluble in acids. It is deliquescent and may spontaneously ignite in air. It is a reducing agent and an ionic compound….
| Potassium Sulfide Identification | |
|---|---|
| CAS Number | 1312-73-8 |
| EC Number | 215-197-0 |
Q. Why is the ball and stick model not accurate?
Ball-and-stick models are not as realistic as space-filling models, because the atoms are depicted as spheres of radii smaller than their van der Waals radii. However, the bonding arrangement is easier to see because the bonds are explicitly represented as sticks.
Q. What happens when you mix potassium and sulfur?
The electrons are transferred from potassium to sulphur, in this reaction, potassium is being oxidised and sulphur is being reduced. Two potassium atoms each lose one electron forming K+ ions. Sulphur gains two electrons forming S2-/2- ions. The resultant formula will be: K2S, bonding in this compound is ionic.
Q. Why is potassium sulfide K2S?
Naming simple ionic compounds: The name of the compound is simply the name of the cation followed by the name of the anion, . e.g, K2S is potassium sulfide. dipotassium sulfide is incorrect because potassium ion is always K+1 and sulfide is always S-2 and therefore the only way to combine them is K2S.
Q. What is the 2 in K2S?
Potassium sulfide
Q. What does the 2 indicate in potassium sulfide?
In potassium chloride KCl, there are 2 kinds of atoms which is oppositely charged. However in K2S, the sulfide ion have a charge of -2, twice the amount of charge the postassium have which is +1. Therefore 2 atoms of potassium needed to make it neutral again.
Q. Why does potassium chloride has the formula KCl?
An ionic compound is made of a metal element and a nonmetal element. In potassium chloride, the metal element is potassium (K) and the nonmetal element is chlorine (Cl), so we can say that KCl is an ionic compound. Because potassium chloride has ions of opposite charges, potassium chloride is classified as a salt.
