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.

How do halogens differ from noble gases?
halogens are much more reactive
Most reactive group of nonmetals?
The Halogens. Fluorine, Chlorine, Bromine, Iodine and Astatine, with Fluorine being the most reactive.
Which family of elements is the most reactive nonmetal family?
The most reactive family of nonmetals is the halogen family.
What are the most active nonmetals called?
halogens
What groups are most likely to react with each other periodic table?
It is about the halogens. They are in the 17th group.
Do halogens form diatomic molecules?
Yes, halogens form diatomic molecules.
Are all halogens diatomic molecules?
All molecules are nuetrally charged.....or else they wouldn't be molecules. Being a diatomic molecule has nothing to do with it.
Which diatomic molecules have single bonds?
The halogens and hydrogen
What family of elements most often exist as diatomic molecules?
The Halogens (Fluorine, Chlorine, Bromine, and Iodine) exist as diatomic molecules, as do hydrogen, nitrogen, and oxygen.
Are Hydrogen Nitrogen Oxygen and the Halogens diatomic molecules?
Yes
The fact that hydrogen forms diatomic molecules makes it similar to what family?
Halogens
What molecules are molecules formed by two or more atoms of the same element that share electrons?
Diatomic molecules. Halogens in particular.
A chemical family whose members exist as reactive diatomic molecules in the gaseous phase?
The Halogen family.
What property do halogens share?
They share many properties, but one is that they all have 7 valence electrons.
Are hydrogen and the halogens the only elements that can form diatomic molecules joined by a single covalent bond?
yes
How do we clasiffy molecular element?
Several chemical elements have diatomic molecules: halogens, hydrogen, oxygen, nitrogen.
What are facts about halogens?
not found free in nature they exist as separate diatomic molecules they produce salts known as halides
