Question

chlorine
determine the ionic name.

ion

write the chemical symbol and charge.

the ionic charge of is achieved when the atom electrons.

Explanation:

Step1: Determine ionic name

Chlorine gains an electron to form an anion. The ionic name is chloride.

Step2: Write chemical symbol and charge

The chemical symbol of chlorine is Cl. When it forms an ion, it has a - 1 charge, written as $Cl^-$.

Step3: Explain ionic - charge formation

Chlorine has 7 valence electrons. It gains 1 electron to achieve a stable octet. So the ionic charge of - 1 is achieved when the atom gains 1 electron.

Answer:

Ion name: Chloride
Chemical symbol and charge: $Cl^-$, - 1
Ionic charge of - 1 is achieved when the atom gains 1 electron.
