That depends on whether it is an ionic or covalent compound. If ionic, the first element has the same name as the element or ion, e.g. NaCl is sodium chloride; NH4Cl is ammonium chloride. If the compound is covalent, then the first element either retains its original name or has a prefix to denote the number of atoms of that element. For example, CO2 is carbon dioxide; P2O5 is di phosphorous pentoxide.

Explain why sulfur aluminide is not a correct name for the ionic compound formed between sulfur and aluminum?

In naming an ionic compound, the cation is named first, with no modification of the element name, and the anion is named secondly, with the element name modified by the suffix "ide". The incorrect name given in the question applies the proper method for the cation to the anion and vice versa.


Which element within a compound is shown first within the compound's name?

In a compound name, the element that appears first is usually the one that is the least electronegative or has the lower oxidation state. This element is named first, followed by the second element with an -ide suffix. For example, in "sodium chloride," sodium is listed first because it is less electronegative than chlorine.


What are the names of the first ten compound elements?

There are elemental compounds, but there is no such thing as a compound element.


What element was named after a cleaning compound which was found to contain larges quantities of it?

The element is called "bromine," which was named after the Greek word "bromos," meaning "stench." Bromine was first extracted from a cleaning compound called "bromine," derived from ancient sources known for its foul odor.


What is the percent composition of ammonium carbonate?

Ammonium carbonate has the formula (NH4)2CO3. To calculate the percent composition, you first find the molar mass of each element and then divide the molar mass of each element in the formula by the formula mass of the compound and multiply by 100 to get the percentage.

What is the first element in a compound that has its ending dropped and ide added?

The first element in a compound that has its ending dropped and "-ide" added is the element that forms a monatomic anion in the compound. This is usually the second element in the modern name of a compound. For example, a compound of sodium and chlorine that contains a sodium cation and a chloride anion is called "sodium chloride". However, a century or more ago, this was often called "chloride of sodium", so that the rule still works even for this style of naming.


What comes first in naming of covalent bonds?

When naming covalent bonds, you first put down the name of the first element. After that, you use a prefix for indicating the number of the atoms of the anion for which you use a suffix. Example: Carbon dioxide.


To name a binary molecular compound you add the suffix -ide to the more ionic of the two elements?

That is partially correct. When naming a binary molecular compound, you add the suffix -ide to the second element in the formula, regardless of its ionic nature. The more electronegative element is usually listed first in the compound formula.


Which element in a compound is named first?

The element that is located further to the left on the periodic table is named first in a compound.


What is the rule used for naming a binary compound composed of a metal bonded to a nonmetal?

For naming a binary compound composed of a metal bonded to a nonmetal, the name of the metal is written first followed by the name of the nonmetal with the ending changed to "-ide." For example, sodium chloride is the name for the compound formed by sodium (metal) bonding with chlorine (nonmetal).


When is it appropriate to use prefixes when naming compounds?

Prefixes are commonly used in naming covalent compounds to indicate the number of each element present in the compound. For example, mono-, di-, tri-, tetra-, penta- are used to denote 1, 2, 3, 4, or 5 atoms of an element, respectively. They are especially useful for distinguishing between different compounds with the same elements but different ratios.


In a formula for an ionic compound which element comes first?

The element that forms the cation (positive ion) comes first in the formula for an ionic compound.


When is a prefix not used in front of the name of an element?

No prefix is used if it is an ionic compound. If it is a binary molecular compound, the prefix mono- is not used in front of the name of the first element. For example, the ionic compound Na2O is sodium oxide, not disodium monoxide, and the molecular compound CO2 is carbon dioxide, not monocarbon dioxide.


Is the prefix mono- used when naming the first element in a formula?

No. Prefixes designating quantity are only ever used for other elements in the compound, never the first one. Example: Carbon Monoxide. The chemical formula is CO, and there is one Carbon atom, just as there is one Oxygen atom, but the Mono- prefix is only affixed to the Oxygen. It should be noted, however, that such prefixes are not always used in chemical formulas. MgCl2 is not named Magnesium Dichloride, just Magnesium Chloride.


What is the rule for naming compounds with only two elements?

The rule is that the metallic (or the less electronegative) element goes first, and the non-metallic (or more electronegative) element goes second. And the second element has an alteration in its name to indicate the formation of a compound. For example, sodium + chlorine = sodium chloride.


True or false the first element in a compound should have no charge?

False, all compounds are electrically neutral.
