Question

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

Explanation:

• For option A: Covalent bonds are present in discrete molecules (e.g., \(H_2O\), \(CO_2\)) and hold the atoms within those molecules together.
• For option C: Covalent bonds can have different bond orders. For example, in \(H_2\) there is a single covalent bond (\(H - H\)), in \(O_2\) there is a double covalent bond (\(O=O\)), and in \(N_2\) there is a triple covalent bond (\(N\equiv N\)).
• For option E: Non - metal atoms share electrons when their orbitals overlap. For instance, in \(HCl\), the \(H\) (non - metal) and \(Cl\) (non - metal) atoms' orbitals overlap to form a covalent bond.

• For option B: Covalent bonds are between non - metal atoms (not metal atoms). Metal atoms are involved in metallic bonding.
• For option D: Ionic bonds (electrostatic attraction between ions) hold ionic compounds together, not covalent bonds.

Answer:

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