a. Molecule versus ion:
Molecule: A molecule is a chemical compound composed of two or more atoms that are covalently bonded together. Molecules can be composed of atoms of the same element (e.g., Oâ‚‚) or different elements (e.g., Hâ‚‚O).
Ion: An ion is an atom or a molecule that has gained or lost one or more electrons, resulting in a net electric charge. If an atom loses electrons, it becomes a positively charged ion (cation), and if it gains electrons, it becomes a negatively charged ion (anion).
b. Covalent bonding versus ionic bonding:
Covalent bonding: Covalent bonding occurs when atoms share electrons to achieve a more stable electron configuration. It typically happens between nonmetals and results in the formation of molecules.
Ionic bonding: Ionic bonding occurs when atoms transfer electrons to each other, resulting in the formation of ions. It typically happens between a metal and a nonmetal and leads to the formation of ionic compounds.
c. Molecule versus compound:
Molecule: As explained above, a molecule is a chemical compound composed of two or more atoms that are covalently bonded together.
Compound: A compound is a substance composed of two or more different elements chemically bonded together. Compounds can be molecules (covalent bonding) or ionic compounds (ionic bonding).
d. Anion versus cation:
Anion: An anion is a negatively charged ion formed when an atom gains one or more electrons.
Cation: A cation is a positively charged ion formed when an atom loses one or more electrons.
