Question

what is the primary factor that determines whether a bond between two atoms will be predominantly ionic or covalent? the physical state (solid, liquid, gas) of the atoms the atomic masses of the atoms the number of neutrons in the atoms nuclei the electronegativity difference between the atoms if the electronegativity difference between two atoms is large (typically greater than 1.7), what type of bond is most likely to form? ionic bond metallic bond polar covalent bond pure covalent bond

Explanation:

1. The electronegativity difference between atoms determines bond type. A small difference leads to covalent bonds, a large one to ionic bonds. Physical state, atomic mass, and neutron number don't determine bond type.
2. When the electronegativity difference between two atoms is large (typically > 1.7), an ionic bond is most likely to form as one atom can completely transfer electrons to the other.

Answer:

1. The electronegativity difference between the atoms
2. Ionic bond
