Question

]Which of the following would you expect to form an ionic bond when combined?

K+ and H+
Ba2+ and Cl-
Se2- and F-
Si and O

Answer 1

Ionic bonds is formed between metal and nonmetal with opposite charges. Metal have (+) charge and nonmetals often have (-) charge.

Choice (a) is wrong because both charges are the same.
Choice (c) is wrong b/c same changes.
Si and O do not have charges for now. (d) is wrong.

Choice (b) is correct. Opposite charges and the ionic compound is BaCl2

Answer 2

Answer: Ba2+ and Cl-

Step-by-step explanation:

Ionic bonds are formed when their is a transfer of electrons between atoms of a metal and a non-metal.

In this case, Ba2+ (metal ion), while Cl- ( non-metal ion). They form the ionic compound called Barium Chloride (BaCl2).
