Vhich statement best describes how many chlorine atoms are needed when making Barium chloride? O2 chlorine atoms are needed because each chlorine atom accepts one of bariums two valence electrons to obtain a full octet and makes chlorine a negatively charged anion. 1 chlorine atom is needed because chlorine accepts one electron from barium to obtain a full octet and makes chlorine a negatively charge anion. 1 chlorine atom is needed because chlorine accepts one electron from barium to obtain a full octet and makes chlorine a positively charged cation. 2 chlorine atoms are needed because each chlorine atom accepts one of bariums two valence electrons to obtain a full octed and makes chlorine a positively charged anion.

**Understanding the Formation of Barium Chloride**

**Question:**
Which statement best describes how many chlorine atoms are needed when making Barium chloride?

**Options:**

1. **Two chlorine atoms are needed** because each chlorine atom accepts one of barium's two valence electrons to obtain a full octet and makes chlorine a negatively charged anion.

2. **One chlorine atom is needed** because chlorine accepts one electron from barium to obtain a full octet and makes chlorine a negatively charged anion.

3. **One chlorine atom is needed** because chlorine accepts one electron from barium to obtain a full octet and makes chlorine a positively charged cation.

4. **Two chlorine atoms are needed** because each chlorine atom accepts one of barium's two valence electrons to obtain a full octet and makes chlorine a positively charged anion.

**Explanation:**
The correct statement is option 1. Barium chloride forms when barium, which has two valence electrons, transfers one electron to each of the two chlorine atoms. This results in two chlorine anions and one barium cation, creating a balanced compound with neutral charge overall.
