6.Barium Form Ions With A Charge Of ___ ?, A. 1+, B.3+, C.2+, D.2-, 7.What Is The Charge Of The Most Stable Ion S?, A.3+, B.2-, C.1-, D.2+,

6.Barium form ions with a charge of ___ ?

a. 1+
b.3+
c.2+
d.2-

7.What is the charge of the most stable ion S?

a.3+
b.2-
c.1-
d.2+

 

Answer:

6. C.

7. B.

Explanation:

6. Barium becomes an ion with a 2+ charge when it reacts with another atom of another element that steals 2 electrons from it

7. The S-atom will gain two electrons in order to complete its octet. Thereby it will carry two units of negative charge and become stable by attaining the configuration of argon. Hence, sulfur has the most stable charge of -2.
