i believe the answer to this is molecule. 

Answer 2

Anion.

Step-by-step explanation:

Ions may be defined as the molecules that contains the positive and negative charge over it. Two main types of ions are cations and anions. The charge on the species depends on the gain and loss of electrons.

Cations has positive charge over them. Ions are negatively charged species as they gain electrons from the other elements. Chlorine is the element with atomic number 17. Chlorine requires one electron to complete its orbit. So, chlorine gain one electron and acquires negative charge over it. Hence, chlorine is anion.

Thus, the correct answer is option (1).
