Dichromate has 7 oxygen atoms (Cr2O7-2)
Any acid that contains hydrogen and an oxyanion is referred to as an oxyacid. * An oxyanion is a polyatomic ion that contains oxygen
No. An oxyanion is a polyatomic negative ion that contains oxygen. Ammonium is a cation (positive ion) and does not contain oxygen.
Phosphate is a polyatomic ion, not an element and so it does not have an atomic number. It is composed of oxygen and phosphorus which have the atomic numbers 8 and 15 respectively.
Yes. Mg2+ is a monatomic ion, but SO42- is a polyatomic ion composed of two elements, sulfur and oxygen.
The -ite or -ate ending in a polyatomic ion is simply an indication of the amount of oxygen atoms present. The -are ending is used in the base form. If the polyatomic ion has one less oxygen atom than the -ate form, the -ite form applies.
SO4 sulfate
Any acid that contains hydrogen and an oxyanion is referred to as an oxyacid. * An oxyanion is a polyatomic ion that contains oxygen
No. An oxyanion is a polyatomic negative ion that contains oxygen. Ammonium is a cation (positive ion) and does not contain oxygen.
Hydroxide is not an element. Instead, it is a polyatomic anion that contains the two elements hydrogen and oxygen.
it's Oxyanion
The polyatomic ion silicate (SiO4 -4) contains one atom of silicon, four atoms of oxygen and has a charge of -4.
The "big wheel" in molybedenum blue is quite big with 532 oxygen atoms in the structure. If you include solid state compounds with network anions such as silicates then the number would be much much bigger, only restricted by the size of the single crystal you could make.
A molecule of CaCO3 contains 5 atoms: 1 calcium atom, 1 carbon atom, and 3 oxygen atoms.
Oxygen
Respectively the higher and the lower state of oxidation of a nonmetal acid-forming oxide.Example:sulfite SO32- from SO2 from S in oxid.state +4forming sulfurous acid H2SO3sulfate SO42- from SO3 from S in oxid.state +6forming sulfuric acid H2SO4The -ate and -ite represent different polyatomic ions containing oxygen; the exact formula and number of oxygen atoms depends on the specific ion. An -ate ion typically has one oxygen atom more than an -ite ion.The -ate and -ite represent different polyatomic ions containing oxygen, the exact formula and number of oxygen atoms depends on the specific ion. An -ate ion typically has one oxygen atom more than an -ite compound. Compounds ending in -ate or -ite are typically salts.
Phosphate is a polyatomic ion, not an element and so it does not have an atomic number. It is composed of oxygen and phosphorus which have the atomic numbers 8 and 15 respectively.
Polyatomic ions ending in -ate in common form contain oxygen.
