Final answer:
Most of the elements on the periodic table are solid at room temperature and under standard conditions. However, there are exceptions to this.
Step-by-step explanation:
Most of the elements on the periodic table are solid at room temperature and under standard conditions. These solid elements may exist as diatomic or polyatomic molecules. For example, I2 (diiodine), O3 (ozone), P4 (tetra phosphorous), and S8 (octasulfur) are all solid elements in the periodic table. However, there are exceptions to this, as some elements are gases or liquids at room temperature.
