Question

which of the phrases describe a chemical bond? select all that apply.
☐ sharing of electrons between atoms
☐ attraction between an atom’s electrons and its nucleus
☐ interaction between ions with opposite charges
☐ interaction between two molecules in solution
☐ attractive force between protons and neutrons

Explanation:

1. "sharing of electrons between atoms": In covalent bonds, atoms share electrons to achieve a stable electron configuration. This is a key feature of chemical bonds (specifically covalent bonds).
2. "attraction between an atom’s electrons and its nucleus": This is the electrostatic attraction within a single atom that holds the atom together, not a chemical bond (which involves interactions between different atoms).
3. "interaction between ions with opposite charges": Ionic bonds are formed by the electrostatic attraction between positively and negatively charged ions (cations and anions). This is a type of chemical bond.
4. "interaction between two molecules in solution": This typically refers to intermolecular forces (like hydrogen bonding, dipole - dipole interactions, or London dispersion forces), which are different from chemical bonds (chemical bonds are intramolecular, within a molecule or between ions to form a compound).
5. "attractive force between protons and neutrons": This is the strong nuclear force that holds the nucleus of an atom together, not a chemical bond (chemical bonds involve interactions between atoms or ions).

Answer:

• sharing of electrons between atoms
• interaction between ions with opposite charges
