### Step-by-Step Solution: 1. **Understanding Isotopes**: - Isotopes are variants of a particular chemical element that have the same number of protons but different numbers of neutrons, resulting in different atomic masses. For example, hydrogen has three isotopes: protium (1H), deuterium (2H), and tritium (3H). 2. **Mendeleev's Periodic Table**: - Mendeleev's periodic table was organized based on increasing atomic mass. Elements were arranged in rows (periods) and columns (groups) according to their properties and atomic masses. ...
