Question

5 multiple answer 3 points which of the following statements about covalent bonds are true? covalent bonds form when atoms of nonmetals are close enough to each other for their orbitals to overlap. covalent bonds hold ionic compounds together. covalent bonds are comprised of metal atoms that share at least some of their valence electrons. covalent bonds can be single, double, or triple bonds. covalent bonds hold the atoms together in discrete molecules.

Explanation:

• Covalent bonds form when non - metal atoms' orbitals overlap (sharing electrons).
• Ionic compounds are held by ionic bonds (electron transfer), not covalent.
• Covalent bonds are between non - metals (sharing valence electrons), not metals.
• Covalent bonds can be single ($\ce{H2}$: $\ce{H - H}$), double ($\ce{O2}$: $\ce{O=O}$), or triple ($\ce{N2}$: $\ce{N\equiv N}$).
• Covalent bonds hold atoms in discrete molecules (e.g., $\ce{H2O}$, $\ce{CO2}$).

Answer:

• A. Covalent bonds form when atoms of nonmetals are close enough to each other for their orbitals to overlap.
• D. Covalent bonds can be single, double, or triple bonds.
• E. Covalent bonds hold the atoms together in discrete molecules.
