This reaction can be very dangerous, so it is important to keep sodium away from water.<\/p>\n<p>Potassium is also a very reactive metal, but it is not as reactive as sodium. Potassium is also kept in kerosene to prevent it from reacting with water and oxygen in the air. However, potassium is not as dangerous as sodium, and it can be handled more safely.<\/p>\n<p>Iodine is a non-metal that is not as reactive as sodium or potassium. Iodine is not kept in kerosene, but it is often stored in dark bottles to prevent it from being exposed to light. Light can cause iodine to decompose, so it is important to store it in a dark place.<\/p>\n<p>Bromine is a non-metal that is more reactive than iodine.
