A group of nonmetallic elements with antimicrobial applications, including bromine, iodine, chlorine and fluorine, are called .

These elements are typically referred to as halogens. Halogens are found in Group 17 of the periodic table and are known for their reactivity, especially with metals, to form salts. Their antimicrobial properties make them effective in various applications such as disinfectants and antiseptics. For instance, iodine is commonly used in wound care, while chlorine is often used in water treatment to kill bacteria and other pathogens. Fluorine, while less often used for direct antimicrobial purposes, plays a critical role in preventing dental cavities by inhibiting bacterial growth in the oral cavity. Overall, the halogens are significant in both industrial and medical fields due to their ability to control microbial growth.
