I believe an abbreviation for an elements name which is what you may be asking for is its chemical symbol, observed on the periodic table of elements.
The cyanide is
A carbon atom has 4 valance electrons and nitrogen has 5. Below is a Lewis-dot-structure of cyanide.
:N≡C.
The carbon atom is still one electron short of having a full octet and so it will seize another electron from almost anything, making the cyanide ion negative and whatever it took the electron from it now positive.

1. Topic: Chemistry
ElementFirst Ionization Energy (kJ/mol) Lithium520Sodium496Rubidium403Cesium376According to the above table, which is most likely to be the first ionization energy for potassium?
2. Topic: Chemistry, Atom
The correct set of four quantum numbers for the valence electrons of the rubidium atom (Z=37) is:
3. Rubidium and cesium are pyrophoric. Here the term pyrophoric means:
- That does not catch fire at all
- That catches fire spontaneously
The net ionic equation is written as H^+(aq) + OH^-(aq) -------> H2O(l)
<h3>What is the net ionic equation?</h3>
The term net ionic equation refers to the equation that shows the ions that underwent a change in the reaction. We have to note that the reaction species here must be ionic species which are able to dissociate into ions in solutions.
Now the first step is to put down the molecular equation. The molecular equation shows the reaction of the compounds as follows;
HCI (aq) + NaOH (ag)-> NaCI (aq) +H2O(l)
Next, we put own the complete ionic reaction equation as follows;
H^+(aq) + Cl^-(aq) + Na^+(aq) + OH^-(aq) -------> Na^+(aq) + + Cl^-(aq) + H2O(l)
Next we have the net ionic equation;
H^+(aq) + OH^-(aq) -------> H2O(l)
