What type of chemical bond is formed when an atom of chlorine and an atom of hydrogen combine to form a molecule of hydrogen chloride (HCl)?
A
A metallic bond is formed between hydrogen and chlorine atoms.
B
An ionic bond is formed by complete transfer of an electron from hydrogen to chlorine.
C
A covalent bond is formed by sharing an electron pair between hydrogen and chlorine.
D
No chemical bond is formed; the atoms remain separate.
검증된 단계별 안내1
Identify the types of atoms involved: hydrogen (H) and chlorine (Cl) are both nonmetals.
Recall that metallic bonds typically occur between metal atoms, so a metallic bond is unlikely here.
Consider ionic bonding, which involves the complete transfer of electrons from a metal to a nonmetal; since hydrogen is a nonmetal and chlorine is also a nonmetal, ionic bonding is less likely.
Understand that covalent bonds form when atoms share electron pairs to achieve stable electron configurations, which is common between nonmetal atoms like H and Cl.
Conclude that the bond in HCl is a covalent bond formed by sharing one pair of electrons between hydrogen and chlorine atoms.
