Within the halogen group, dispersion forces account for a lot of their physical properties. Dispersion forces are caused by the random motion of electrons causing a "pile up" of electrons very briefly on a certain side of the atom. This causes a slight difference in charge across the length of the atom, which in turn causes a slight attraction or repulsion on the part of another nearby atom. Multiplied billions of times across billions of atoms, it creates a measurable force. Dispersion forces are the reason why fluorine (F) and chlorine (Cl) are gases, bromine is a liquid (Br), and iodine (I) is a solid. The more electrons there are (going top to bottom down the halogens), the more dispersion forces you have.
halogens are much more reactive
The Halogens. Fluorine, Chlorine, Bromine, Iodine and Astatine, with Fluorine being the most reactive.
The most reactive family of nonmetals is the halogen family.
halogens
It is about the halogens. They are in the 17th group.
Yes, halogens form diatomic molecules.
All molecules are nuetrally charged.....or else they wouldn't be molecules. Being a diatomic molecule has nothing to do with it.
The halogens and hydrogen
The Halogens (Fluorine, Chlorine, Bromine, and Iodine) exist as diatomic molecules, as do hydrogen, nitrogen, and oxygen.
Yes
Halogens
Diatomic molecules. Halogens in particular.
The Halogen family.
They share many properties, but one is that they all have 7 valence electrons.
yes
Several chemical elements have diatomic molecules: halogens, hydrogen, oxygen, nitrogen.
not found free in nature they exist as separate diatomic molecules they produce salts known as halides
