The family that contains disinfectants is the noble gases transition metals strong metals halogens

I think the correct answer from the choices listed above is the last option. The family that contains disinfectants is the halogens. This group includes  the elements fluorine, chlorine, bromine, iodine, and astatine. Disinfectants are chemical agents that inhibit or kill microorganisms on inanimate objects.

If a hydrogen atom is neutral, it must also have  one electron. an oxygen atom (o) has an atomic number of eight (8). this means a neutral oxygen atom has eight protons and eight electrons. the element actium (ac) has an atomic number of 89, so it has 89 protons and 89 electrons in a neutral atom
