Question

when sodium atoms (na) and chlorine atoms (cl) join to make sodium chloride, or table salt, they form an ionic bond. using this information, which pair of elements is most likely to form an ionic bond?
potassium (k) and fluorine (f)
aluminum (al) and aluminum (al)
sulfur (s) and oxygen (o)
calcium (ca) and neon (ne)

Explanation:

Step1: Recall ionic bond formation

Ionic bonds form between a metal and a non - metal.

Step2: Analyze each option

• Potassium (K) is a metal and fluorine (F) is a non - metal.
• Aluminum (Al) and aluminum (Al) are the same metal, no ionic bond.
• Sulfur (S) and oxygen (O) are both non - metals, form covalent bonds.
• Calcium (Ca) is a metal but neon (Ne) is a noble gas which is very stable and does not readily form bonds.

Answer:

potassium (K) and fluorine (F)
