Metallic bonds

Explanation:

Metals consist of closely packed cations and loosely held valence electrons rather than neutral atoms. The valence electrons of atoms in a pure metal can be modeled as a sea of electrons. Metallic bonds are the forces of attraction between the free-floating valence electrons and the positively charged metal ions.

answer; the numbers of valence electrons in the acetic acid molecule (ch3co2h) is 24;
