Question

part 1: phenomenon – why does salt taste salty?
you eat a french fry sprinkled with table salt (nacl). sodium (na) is a soft, reactive metal.
chlorine (cl) is a poisonous green gas. but together, they make the safe and tasty salt you eat
every day!

question: what kind of bond forms when sodium (a metal) bonds with chlorine (a nonmetal)
to make table salt?
a. covalent bond
b. ionic bond
c. metallic bond
d. hydrogen bond

Explanation:

To determine the bond type between sodium (metal) and chlorine (nonmetal) in NaCl:

• Ionic bonds form between metals (which lose electrons) and nonmetals (which gain electrons). Sodium (Na) donates an electron to chlorine (Cl), forming \( \text{Na}^+ \) and \( \text{Cl}^- \) ions, which are held together by electrostatic attraction (ionic bonding).
• Covalent bonds involve electron sharing (between nonmetals), metallic bonds involve a sea of electrons (in metals), and hydrogen bonds are weak attractions (e.g., in water). These do not apply here.

Answer:

B. Ionic bond
