SO4 sulfate
covalent compounds is two nonmetals. example: phosphorus and oxygen are a covalent compound. ionic compounds is when you have a metal and a nonmetal or a metal and a polyatomic.
Hydroxide is not an element. Instead, it is a polyatomic anion that contains the two elements hydrogen and oxygen.
- If you think only to isolated elements all these elements can form polyatomic compounds.- Calcium and sodium form ionic compounds.- H, N, O, Cl can form ionic or covalent compouds.
The polyatomic ion silicate (SiO4 -4) contains one atom of silicon, four atoms of oxygen and has a charge of -4.
SO4 sulfate
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.

it's Oxyanion

how can chromium form two diffrent compounds with oxygen? well some compounds including baking soda,are composed of more than two elements because theycontain polyatomic ions. ( answered question bye veronica wilson:)
metal oxides
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.
