Question

question 2
why do ionic bonds form between metals and nonmetals?
○ ionic bonds form between metals and nonmetals because they both form positive ions.
○ ionic bonds form between metals and nonmetals because metals form positive ions and non-metals form negative ions.
○ ionic bonds form between metals and nonmetals because they are close to each other on the periodic table.
○ ionic bonds form between metals and nonmetals because they have the same number of valence electrons.

Explanation:

Ionic bonds rely on electrostatic attraction between oppositely charged ions. Metals have low ionization energy, so they lose valence electrons to form positive cations. Nonmetals have high electron affinity, so they gain electrons to form negative anions. The other options are incorrect: metals do not form negative ions, metals and nonmetals are far apart on the periodic table, and they have different numbers of valence electrons.

Answer:

Ionic bonds form between metals and nonmetals because metals form positive ions and non-metals form negative ions.
