How many extra electrons does a sulphate ion have?
Sulfate is a polyatomic ion with 1 sulfur (6 valence electrons), 4 oxygens (4 x 6 valence electrons = 24 e-) and a charge of -2 (2 valence electrons). If we add all the electrons together we get 32 valence electrons with which to make bonds and lone pairs around the atoms in the ion.
Why does the sulfate ion have a 2 charge?
Sulfur can have either a partial positive charge or a partial negative charge. Hydrogen Sulfide = H2S, which can break down to H+ and HS- [sort of like water]. We would need 32 valence electrons for 4 full outer shells(8×4) but only have 30. Thus the charge is 2- for the ion.
How so4 2 is formed?
The sulphate ion is mainly composed of sulphur and oxygen atoms. Here, sulphur is the central atom and it is surrounded by four oxygen atoms that are located at equal distances in the plane. As for the bonding, 2 of the oxygen atoms form S=O. bonds and the other two form S-O- bonds.
Where do ions gain electrons from?
The outer shells of non-metal atoms gain electrons when they form ions: the ions formed are negative, because they have more electrons than protons. the ions formed have full outer shells.
Where do sulfates come from?
Most of the sulfate in water comes from dissolved minerals, namely sodium sulfate (salt cake), magnesium sulfate (Epsom salts) and calcium sulfate (gypsum). Sulfate can also come from fertilizer or sewage treatment.
What is sulphate made up of?
The sulphate ion is composed of sulphur and oxygen atoms. Here, sulphur is the central atom and it is surrounded by four oxygen atoms that are located at equal distances in the plane. As for the bonding, 2 of the oxygen atoms form S=O. bonds, and the other two form S-O- bonds.
What is the meaning of so4 2?
1. a salt or ester of sulfuric acid. 2. to combine, treat, or impregnate with sulfuric acid, a sulfate, or sulfates.
Is so4 2 ionic or covalent?
The Lewis structure for the sulfate ion consists of a central sulfur atom with four single bonds to oxygen atoms. This yields the expected total of 32 electrons. Since the sulfur atom started with six valence electrons, two of the S-O bonds are coordinate covalent.

How are ions formed by electron loss or gain?
Metal atoms lose the electron, or electrons, in their highest energy level and become positively charged ions. Non-metal atoms gain an electron, or electrons, to become negatively charged ions.
How ionic bond is formed?
An ionic bond is formed by the complete transfer of some electrons from one atom to another. The atom losing one or more electrons becomes a cation—a positively charged ion. The atom gaining one or more electron becomes an anion—a negatively charged ion.
