Question

answer each question about the following atom when it becomes an ion. chlorine determine the ionic name. ion write the chemical symbol and charge. cl the ionic charge of is achieved when the atom gains 1 electrons.

Explanation:

Step1: Recall chlorine's ion - formation

Chlorine is a non - metal and gains electrons to form an ion.

Step2: Determine ionic name

When chlorine gains an electron, it forms a chloride ion.

Step3: Identify chemical symbol and charge

The chemical symbol of chlorine is Cl. When it gains one electron, it has a charge of - 1, written as $Cl^-$.

Step4: Explain ionic charge formation

Chlorine has 7 valence electrons. It gains 1 electron to achieve a stable 8 - electron outer shell, resulting in an ionic charge of - 1.

Answer:

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