Firstly, we need to understand that I2O4 is not a chemical substance that exists in reality. When combined, iodine (I2) and oxygen (O2) form other compounds such as I2O5 (pentoxide iodine) or IO (iodine monoxide), but there is no I2O4.
However, to help students better understand chemical compounds, we will discuss I2 and O2 separately.
Iodine (I2) is a nonmetal element in the periodic table, belonging to the halogen group. It appears as dark gray crystalline solid, slightly purple when it evaporates. Iodine has an atomic mass of about 126.9.
Oxygen (O2) is a vital chemical element, belonging to the chalcogen group. It is a colorless, odorless and tasteless gas, essential for the life of all organisms.
When they combine with each other, iodine and oxygen create compounds like I2O5, a white solid with a characteristic odor.
I2O5 is a strong oxidizing agent that can react with many other substances such as metals, acids, salts… However, it is not easily produced in laboratory conditions as it requires high temperature and pressure.
Above is some basic information about iodine, oxygen and their compounds. We hope this will help students better understand the chemical substances in the periodic table.
