Ionic compounds do not contain discrete molecules but rather a repeating pattern of positive and negative ions in a crystal lattice. The charges on the ions already indicate the ratio of the elements present, so prefixes are not needed to specify the number of atoms like in covalent compounds.

Do you use the naming prefixes when naming ionic compounds?

No, formulas of ionically bonded compounds can be figured out without prefixes and understanding of how many electrons are gained/lost. In covalent bonds, prefixes are needed and without them the formulas and quantities couldn't be determined.


Why are prefixes not needed in naming ionic compounds?

Ions combine in only one ratio, so prefixes are not needed.


Are Ionic compounds named using numerical prefixes?

No, Ionic compounds are named using the names of the individual ions that make up the compound. Numerical prefixes are used in naming molecular covalent compounds.


Why are prefixes used in naming ionic compounds?

two ions can combine in only one combination


Why aren't prefixes used in naming ionic compounds?

Prefixes are not used in naming ionic compounds because the charges of the ions involved determine the ratio in which they combine, thus eliminating the need for numerical prefixes to specify the number of atoms of each element. Ionic compounds are named using the names of the individual ions involved, without using prefixes to indicate the number of atoms.


Why is Al2O3 is named aluminum oxide without prefixes?

Aluminum oxide is named without prefixes because aluminum typically forms a 3+ cation, while oxygen forms a 2- anion. The charges balance in a 1:1 ratio, so no prefixes are needed to indicate the relative numbers of each element present in the compound.

Why do Greek prefixes appear in the names of ionic or covalent compounds?

Greek prefixes are used in the naming of covalent compounds to indicate the number of atoms of each element present in the compound. These prefixes help in specifying the exact ratio of elements in the compound. In ionic compounds, Greek prefixes are not used because the compounds consist of ions with fixed ratios, so the prefixes are not needed.


Do Ionic compounds use prefixes mono di tri?

yeah.. mono-1 di-2 tri-3 tetra-4 penta-5 hexa-6 hepta-7 octa-8 nona-9 deca-10 dodeca-20 The real answer is NO. The prefixes are only used in Type III compounds which are Covalent Bonds. Ionic Bonds only need the ending -ide.


Do Greek Prefixes appear in the names of ionic or covalent compounds?

because they are the 1st discoverers.


When naming binary ionic or covalent compounds change the suffix of the anions name to what?

When naming binary ionic compounds, the suffix of the anion's name is changed to "-ide." For covalent compounds, the suffix of the anion's name does not change.


Why do you put prefixes in front of molecular compositions but not ionic compounds?

Just because
