If you count up the number of valence electrons (including the extra electron from the -1 charge) you get: S + C + N + e- = 6 + 4 + 5 + 1 = 16 Divide this by 2 to get the electron pairs: 16/2 = 8 Now connect the atoms: S-C-N That used up two pairs... 8 - 2 = 6 left. Now place the remaining pairs of electrons around the outside atoms. this is hard to picture, but you put three around the sulfur before it reaches 8 electrons (the most it can have) and three around the nitrogen before it has 8 electrons. Finally, look at each atom to confirm it has 8 electrons around it. Sulfur has 8 (3 lone pairs and a bond), nitrogen has 8 (also 3 lone pairs and a bond), but carbon only has 4 (two bonds). To fix this, start forming double bonds using an electron pair each from the nitrogen and the sulfur. When you do this you get: S=C=N (with two lone pairs on both the S and the N).

What is the molecular structure of SCN- in terms of its Lewis structure?
The molecular structure of SCN- in terms of its Lewis structure consists of a central sulfur atom bonded to a nitrogen atom and a carbon atom. The sulfur atom has a lone pair of electrons, and there is a triple bond between the sulfur and nitrogen atoms.
What are the different resonance structures of the SCN- ion?
The SCN- ion has two resonance structures. In one structure, the nitrogen atom carries a negative charge, while in the other structure, the sulfur atom carries the negative charge. These resonance structures show the distribution of electrons within the ion.
What is the structure for SCN?
with 16 valence electrons it is a linear structure. lS = C = Nl
What is the significance of the SCN structure in database management systems?
The SCN (System Change Number) structure in database management systems is significant because it helps track and manage changes made to the database. It acts as a timestamp for transactions, ensuring data consistency and enabling recovery in case of system failures. This structure plays a crucial role in maintaining the integrity and reliability of the database system.
What is the name of scn?
The Self-Controlled Neurofeedback training is referred to as "SCN".

What are scn numbers?
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.

When was SCN - TV station - created?
SCN - TV station - was created in 2003.
What is correct decreasing order of conductivity in the following SCN CIO4 CI I OR CIO4 CI SCN I OR CI I SCN CIO4 OR I CI CIO4 SCN?
The correct decreasing order of conductivity is: CIO4 > SCN > CI > I. Conductivity generally increases with the presence of more ions in solution.

What is the formula of tungten and thiocyanate together?
Sn(SCN)4 or Sn(SCN)2
A possible Lewis structure of a molecule for which more than one Lewis structure can be written is called?
Resonance structure.
Is scn- polar?
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.
