Question

Describe how to write an ion

Answer 1

Answer:

When writing an ion, state symbols of the substances must be clearly indicated.I HOPE IT HELPS I MADE AN EXAMPLE TOO:)

Explanation:

Example:

Write the ionic equation for the word equation

Sodium chloride(aq) + silver nitrate(aq) → silver chloride(s) + sodium nitrate(aq)

Solution:

Step 1: Write the equation and balance it if necessary

NaCl(aq) + AgNO3(aq) → AgCl(s) + NaNO3(aq)

Step 2: Split the ions. (Only compounds that are aqueous are split into ions.)

Na+(aq) + Cl-(aq) + Ag+(aq) + NO3-(aq) → AgCl(s) + Na+(aq) + NO3-

Step 3: Cancel out spectator ions. (Spectator ions are ions that remain the same in their original states before and after a chemical reaction.)

Ionic Equation

Step 4: Write a balanced ionic equation

Ag+(aq) + Cl-(aq) → AgCl(s)

Answer 2

Answer:

Cations (positively-charged): With a superscript + (e.g. $\mbox{Na^{+}}$)

Anions (negative-charged): With a superscript - (e.g. $\mbox{Cl^{-}}$)

Explanation:

An ion is an atom that carries some sort of negative or positive charge due to losing or gaining electrons in bonding with another atom. A cation, a positively-charged ion, loses an electron in the bonding process, and is written with a small plus sign superscript, while an anion, a negatively-charged ion, is written with a small minus sign. For example, a sodium cation in a sodium chloride molecule would be written like $\mbox{Na^{+}}$, and the corresponding chloride anion would be written like $\mbox{Cl^{-}}$)
