Question

An ionic bond would most likely form between atoms of which of these pairs? A. oxygen and oxygen B. magnesium and oxygen C. magnesium and magnesium User: What is an ionic bond? A. the attraction positive ions have for free electrons B. the force that holds the valence electrons to the atom C. the attraction and bonding of ions with equal opposite charges D. the bonding of ions to the same element atoms of neutral charge

Answer 1

Qn1)B
qn2)C

This is because a nonmetal(oxygen) and a metal(magnesium) form ionic bond.
An ionic bond is strong electrostatic forces of attraction between positive and negative ions (opposite ions)

exp: Mg2+ + O2- ---> MgO
