In INORGANIC chemistry the names of metals come first.
Nomenclature in ORGANIC chemistry is very complicated, but you'll find all 'offical' rules in the I.U.P.A.C NOMENCLATURE RULES.

What are the names of the first ten compound elements?
There are elemental compounds, but there is no such thing as a compound element.
Which element comes first in a chemical formula?
The order of compounds doesn't make a big difference, but the order for each of the elements within the compound does.Example:Ca + Cl2 -> CaCl2As you can see on the right side, Calcium is placed in front of Chlorine, because in this case Calcium is a cation (positive ion) and Chlorine is an anion (negative ion). In compounds like this, the cation (positive) element is placed first, and the anion (negative) element is placed second.The order on the left side doesn't really matter, seeing as there, Calcium and Chlorine are not bonded, although you will typically find that even though they are separate, they are still usually placed positive ion first and negative ion second, as shown.
Does oxygen and barium form an ionic compound?
Barium can form two distinct compounds with oxygen as the only other element in the compound: barium oxide with formula BaO and barium peroxide with formula BaO2. The first of these compounds is more common and more stable.
When naming a compound what gets changed about the first element?
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.
Is zirconium oxide an ionic compound?
Yes: bonds between calcium cations and oxide anions. Each of these has an absolute value of electric charge of 2, calcium being positive and oxide negative, so that the compound is neutral with only a single one of each kind of ion it contains.
What are the names of the first ten compound elements?
There are elemental compounds, but there is no such thing as a compound element.
True or false the first element in a compound should have no charge?
False, all compounds are electrically neutral.
What are two elements combined to form a compound?
The first element is H20 and the second is 02 when these 2 compounds mix they form water
When is it appropriate to use prefixes when naming compounds?
Almost always. Especially when there are more than one atom of the first element in the compound.
Are organic compounds the first carbon compounds that scientists studied?
what was the first carbon compound scientist studied
Who was the first to classify materials as compounds?
The concept of compound is probably as old as the concept of "element". Robert Boyle, the key figure in the transition from alchemy to chemistry, was one was one of the first to try to distinguish "compounds" from other types of matter.
What was used to make the first compounds of an element in the group gases?
Xenon was the first noble gas from which a compond was made. The first isolated compound was the hexafluoroplatinate salt Xe+ PtF6-
What can compounds be broken down too?
The first step in breaking up a compound leads to chemical elements. Breaking up an element leads only to subatomic particles.
The first organic compound to be created out of inorganic compounds was?
Urea
Should the first element in a binary compound have no charge.?
No
Which symbol comes first in a chemical formula?
This depends on the type of compound. For metallic compounds, the metal comes first. For nonmetallic inorganic compounds the more electropositive element comes first. For MOST organic compounds, carbon comes first.
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.
