That depends on what you mean by harmful; any chemical can be harmful in the right (or wrong) situation. If not used or stored correctly, they can all damage property and cause serious injury - even death.
Halogens Apex ;)
Halogens are all non-metals, they are all very reactive, and they are all colorful.
No, halogens do not have high density. Halogens are all nonmetals and are typically lighter than metals, so they have lower densities.
Fluorine is the most electronegative element and can displace all other halogens from the solution of their salts.
No, halogens are not the basis of all fossil fuels. Fossil fuels are primarily made up of hydrocarbons, which are compounds of hydrogen and carbon. Halogens, like chlorine and fluorine, are not typically found in significant amounts in fossil fuels.
Halogens are highly reactive, and they can be harmful or lethal to biological organisms in sufficient quantities. This reactivity is due to highelectronegativity and high effective nuclear charge.
Halogens Apex ;)
Yes they are - they are all toxic and corrosive.

All halogens are very reactive chemical elements anf form anions.

Halogens are highly reactive, and don't lose their electrons easily. Halogens are all in group 17 of the periodic table, meaning they all have 17 valence electrons.
Halogens are not the basis of all fossil fuels. Fossil fuels are primarily composed of hydrocarbons, which are compounds made of hydrogen and carbon. Halogens like chlorine, bromine, and fluorine are not key components of fossil fuels.
No, halogens are not the basis for all fossil fuels. Fossil fuels primarily consist of hydrocarbons, which are compounds made of hydrogen and carbon. Halogens, such as chlorine, fluorine, bromine, and iodine, do not play a significant role in the formation of fossil fuels.
Various chemicals can harm the ozone layer.The ones containing halogens are the most harmful.
