The Sulfate, SO4
SO4-2The sulfate ion is a polyatomic ion made up of one sulfur atom and four oxygen atoms, that exists only if it can gain 2 electrons (from some metal cation or cations). It has a charge of -2. Note that this is the sulfate ion and not the sulfiteion.
Yes. Mg2+ is a monatomic ion, but SO42- is a polyatomic ion composed of two elements, sulfur and oxygen.
Zinc sulphate is a COMPOUND. It is made up of three elements, they are Zinc, Sulphur and Oxygen. The chemical formula is 'ZnSO4'. This tells us that there is one atom of zinc, one atom of sulphur and 4 atoms of oxygen. In normal ambient conditions it is a white solid.
The systematic name for the compound Fe2(SO4)3 is iron(III) sulfate. In this compound, the iron ion has a +3 charge, hence denoted as iron(III), and sulfate is a polyatomic ion with a -2 charge, requiring three sulfate ions to balance the charge of two iron ions.
The polyatomic ion Na2SO4 is called sodium sulfate.
In copper sulfate (CuSO4), the polyatomic ion is SO4^2-, which is covalently bonded. The copper ion (Cu) is not part of the polyatomic ion and is ionically bonded to the sulfate ion.
The polyatomic ion in magnesium sulfate is SO4(2-), which is a covalent compound consisting of sulfur and oxygen atoms bonded together. Therefore, in magnesium sulfate (MgSO4), the portion that is a covalently bonded polyatomic ion is the sulfate ion (SO4(2-)).
The sulfate ion (SO42-) is the polyatomic ion
An example of a compound composed of a metal and a polyatomic ion is magnesium sulfate (MgSO4). In this compound, magnesium is the metal, and the sulfate ion (SO4) is the polyatomic ion.
Magnesium sulfate, MgSO4 is a salt containing the magnesium ion Mg2+ and the polyatomic ion, sulfate, SO42-. These ions are ionically bonded. However within the sulfate ion, sulfur is covalently bonded to oxygen.
Sodium sulfate is an ionic compound, composed of monatomic and monovalent sodium cations and polyatomic and divalent sulfate anions. The anions are internally covalently bonded, but are not compounds because they are not electrically neutral.
The Sulfate, SO4
SO4
Sulfate is a polyatomic ion composed of sulfur and oxygen atoms, so it is considered a compound.
A charged group of covalently bonded atoms is called a polyatomic ion. These ions have a net positive or negative charge due to an imbalance in the number of protons and electrons. Examples include sulfate (SO4^2-) and ammonium (NH4^+).
NO3 -
Potassium sulfate contains both covalent and ionic bonding. Potassium cations are bonded ionically to the polyatomic sulfate anions, and these anions are internally bonded covalently.
