Why is Al2O3 is named aluminum oxide without prefixes?
Aluminum oxide is an ionic compound. Prefixes are not used in naming ionic compounds, but are used in naming binary molecular compounds.
Why do Greek prefixes appear in the names of ionic or covalent compounds?
Different compounds can be formed of the same elements, so the prefixes are needed to distinguish different binary compounds.
How are bases named?
Cytosine pairs with guanine Adenine pairs with thymine (or with uracil in RNA)
What is H3AsO4?
The molecule above should be NH4SO4.It is ammonium sulphate
What are the covalent compounds?
Covalent compounds share electronsCovalent compounds are neutralB.The compounds share electrons.C.The compounds show no charge.D.The compounds are named with Greek prefixes.

What kind compounds are named using prefixes?
Type your answer here... Covalently bonded molecules
What kind of compounds are named using prefixes?

In naming a binary ionic compound the name of the appears first followed by the name of the?
Binary ionic compounds are named by writing the name of the action, followed by the name of the anion. Potassium bromide is an example of an ionic compound.
What is H3AsO4?
The molecule above should be NH4SO4.It is ammonium sulphate
How are nonmetals in ionic compounds named?
Nonmetals(anion) are written second after the metal(cation).
How are polyatomic ions named in ionic compounds?
If the compound contains a polyatomic ion, simply name the ion.
What are the covalent compounds?
Covalent compounds share electronsCovalent compounds are neutralB.The compounds share electrons.C.The compounds show no charge.D.The compounds are named with Greek prefixes.
Ionic compounds are named by writing the cation name followed by the anion name?
Yes - that is usually correct
What is the difference between the composition of binary ionic and binary molecular compounds?
Binary molecular (covalent) compounds are named according to the number of atoms in the compound. Each number has it's own prefix.List of Prefixes:mono-di-tri-tetra-penta-hexa-hepta-octa-nona-deca-For example:CO2 = Carbon dioxideBr2O7 = Dibromine heptoxide (note "a" is sometimes excluded for word flow)Br4Cl8 = Tetrabromine octachlorideIn comparison, ionic compounds don't have prefixes but the anion (second ion) always has the suffix "-ide"For example:Li2O- Lithium oxideCaBr2- Calcium bromideAl2O3- Aluminum oxideThe reason you don't need prefixes to specify the number of ions in an ionic compound is because the charges of the two atoms add to zero (you could figure it out if you wanted to based on the given information).
