Why must oxidation numbers be assigned to the elements before writing a chemical formula?
The oxidation numbers of the elements in a chemical formula, some of which will be positive and others of which will be negative, when multiplied by the numbers of atoms with each oxidation number, must produce products that add to a net result of zero.
What is one way to keep track of valence electrons in an ionic compound?

What is the oxidation number of each oxygen atom in ozone?
Oxidation numbers are an invention of chemists; they are simply an accounting scheme that helps chemists to keep track of things in a redox reaction. There are several different ways to assign oxidation numbers in ozone. The only fixed point that all would agree on is that the sum of oxidation numbers on the three atoms must come to zero. Argument 1: All 3 atoms are oxygen, so they all have the same electronegativity, so the oxidation numbers must be 0,0, and 0 Argument 2: When writing the formula of ozone and trying to obey the rules of valence, you have to use formal charge. The formula could be written O=O(+)-O(-) In this case the oxidation numbers must be assigned as 0,+1, and -1 Argument 3: The formulation of argument 2 is correct BUT both "end" oxygen atoms are in symmetrically identical environments, and the formula written above is just one of two resonance structures. The symmetry of the molecule must be recognised, and so the oxidation numbers are -1/2 , +1, and -1/2 You can find professional chemists who will argue quite strongly for any one of these three assignments. None of them is really "right" or "wrong". It is all a matter of how you want to do your accounting. (But just sit back and nod wisely if you find a chemist who is arguing passionately for a particular assignment).
What is the electron dot notation for germanium?
4 individual dots around the symbol "Ge" (same as for carbon).See the Related Questions to the left for how to count the valence electrons, which is what the electron dot notation keeps track of.1..............aplus
Why does carbon conduct electricity if it is a non metal?
Carbon is used as a conductor in many applications. One common conductor, automotive spark plug wires, is actually a carbon impregnated chord. A common problem in high voltage electrical systems, such as automotive ignition secondary circuits, is "carbon tracking". A distributor cap, for example, may arc from one terminal to another, leaving a carbon track behind. The current will now follow that carbon path very readily and this is one reason secondary circuit (high voltage) components have to be replaced periodically.

What type of sales data does the website The Numbers track?
The website 'The Numbers' doesn't actually track sales data. It is the website for the movie titled 'The Numbers.' There are a lot of different sites that include 'the numbers' in their name that track a wide variety of data.

Are accession number in library science on bar code of books?
Accession numbers in library science are unique identifiers used to track and manage library materials. These numbers are typically assigned sequentially to each item in the library’s collection and are often included on the barcodes of books to help with organization and inventory management.

What is a fedex reference number?
A FedEx reference number is a number provided by the sender to track a package. It can be a combination of numbers and letters that helps identify a specific shipment. This number is different from the tracking number assigned by FedEx.
