The scn is an ever-increasing number. It can be used to determine the "age" of the database and its component datafiles.
The current system SCN can be queried using dbms_flashback.get_system_change_number.
The SCN of the last checkpoint can be found in v$database.checkpoint_change#.
The SCN is needed in a flashback table .. to scn ... statement.
Within this context, SCN stands for System Change Number.
To assign oxidation numbers for SCN-, first we assign oxidation number x to S. Then, we know that the overall charge of SCN- is -1, and N is -3 in most cases. By summing up the oxidation numbers (-1), we can solve for x as +2.

The formula for the thiocyanate ion is SCN-.
SCN - TV station - was created in 2003.
The correct decreasing order of conductivity is: CIO4 > SCN > CI > I. Conductivity generally increases with the presence of more ions in solution.
The Self-Controlled Neurofeedback training is referred to as "SCN".
Sn(SCN)4 or Sn(SCN)2
Your terms are not clear. If you mean SCN (chem.) it's polar (yes, ions can be polar). If you ScN (Transistor), it can be either; it's a switching function.
The charge is -1.
Ba(SCN)2 is an ionic compound due to the presence of the barium cation (Ba^2+) and thiocyanate anion (SCN^-).
There is no specific element with the symbol SCN on the periodic table. SCN commonly refers to the thiocyanate ion (SCN-) which is a polyatomic ion. It is a combination of sulfur (S), carbon (C), and nitrogen (N), commonly found in compounds.
I would like to know if SCN Publishing in Apollo Beach Fl is a scam?
