Question

The periodic table shows metals, nonmetals, and noble gases. Which two elements will most likely form an ionic bond?

A.krypton and lithium
B.magnesium and silicon
C.calcium and potassium
D.iodine and chlorine

Answer 1

The correct answer from the answers provided is B) Magnesium and Silicon.

Answer 2

Answer;

B. Magnesium and silicon

Explanation;

• Ionic bond is a type of bond that is formed between a metal and a non metal. This type of bond occurs as a result of transfer of electrons where an atom of a metal looses electrons and that of a non metal gains electrons. Consequently, the atoms involved attain a stable configuration, where one becomes a cation and the other becomes an anion.
• In this case, magnesium and silicon will form an ionic bond because magnesium is a metal and silicon is a non metal, such that magnesium requires to loose two electrons and silicon requires to gain four electrons to attain a stable configuration and form an ionic compound.
