which would be the correct formula for a compound of strontium (sr) and chlorine (cl)?\na. srcl\nb. srcl₂\nc. srcl₃\nd. sr₂cl\ne. sr₂cl₃
Answer
Explanation:
Step1: Determine strontium's valence
Strontium (Sr) is in group 2, has a +2 valence.
Step2: Determine chlorine's valence
Chlorine (Cl) is in group 17, has a -1 valence.
Step3: Balance charges
To balance +2 and -1 charges, need 2 Cl for 1 Sr.
Answer:
B. $SrCl_2$
