Ba and O, Fe and
.
Explanation
## Step1Covalent bonds occur when electrons are shared between two atoms. Typically, these are nonmetals in the periodic table, as metals tend to donate their electrons, creating an ionic bond. ## Step2We need to check each combination of elements to determine whether they would form a covalent bond.## Step31. O and N: Oxygen (O) and Nitrogen (N) are both nonmetals, hence they will form a covalent bond.2. N and F: Nitrogen (N) and Fluorine (F) are also both nonmetals and will form a covalent bond.3. Ba and O: Barium (Ba) is a metal and Oxygen (O) is a nonmetal. As a general rule, metals and nonmetals necessarily form ionic bonds due to the tendency of the metal to give up electrons to the nonmetal.4. P and Cl: Phosphorous (P) and Chlorine (Cl) are both nonmetals, and will form a covalent bond.5. Fe and
: Iron (Fe) and Oxygen (O) have the same sort of relationship as O and Ba: one is a metal, and one is a non-metal, meaning they will form an ionic bond.## Step4From the options, Ba and O and Fe and O would not form covalent bonds, due to the presence of a metal and a nonmetal in both conditions.
