What Makes Them Similar? When you look at our descriptions of the elements fluorine and chlorine, you will see that they both have
seven electrons in their outer shell
. That seven-electron trait applies to all of the halogens. … Fluorine is the most reactive and combines with most elements from around the periodic table.
What do fluorine chlorine and bromine have in common?
The elements that belong to the same group in the periodic table possess same number of
valence electrons
. Fluorine, chlorine, bromine and iodine, all belong to the same group, Group 17 of the periodic table. So, all these elements possess same number of valence electrons.
What do hydrogen fluorine and chlorine have in common?
They readily combine with metals to form
salts
. They have seven valence electrons in their outer shell. They are highly reactive and electronegative. They all exist as diatomic molecules (two atoms) when in their pure form.
What does fluorine and chlorine form?
Fluorine, F
2
, reacts with chlorine, Cl
2
, at 225°C to form
the interhalogen species ClF
. The trifluoride chlorine(III) fluoride is also formed and the reaction does not go to completion.
Why is chlorine chemically similar to fluorine?
Any element with 7 electrons in the outermost shell will have similar properties
. Thus other elements in the same column of the periodic table as chlorine will have similar properties. Elements in this column form what is called the Halogen series, which is composed of fluorine, chlorine, bromine, iodine, and astatine.
Why chlorine is less reactive than fluorine?
The reactivity is the halogens ability to gain an electron, so number of electrons already in the atom plays a vital role.
Chlorine has more electrons so repels a reacting electron with greater force than fluorine
, making it less likely to react.
Why are group 17 called halogens?
The group 17 elements include fluorine(F), chlorine(Cl), bromine(Br), iodine(I) and astatine(At) from the top to the bottom. They are called “halogens”
because they give salts when they react with metals.
Which is the rarest element on the Earth?
A team of researchers using the ISOLDE nuclear-physics facility at CERN has measured for the first time the so-called electron affinity of the chemical element
astatine
, the rarest naturally occurring element on Earth.
Is fluorine a metal?
Fluorine (F) is the first element in the Halogen group (group 17) in the periodic table. … It is
a nonmetal
, and is one of the few elements that can form diatomic molecules (F2).
Why do chlorine bromine and iodine have different physical states?
An increase in size of the molecules requires the element to be at a higher temperature before there is a change in its physical state. As a result fluorine and chlorine are present as gases at room temperature,
bromine is a liquid, and iodine is a gas
.
Can fluorine reacts with water?
Fluorine vigorously reacts with water to form hydrogen fluoride and oxygen
. Sometimes, instead of oxygen, ozone is produced. In the above reactions, fluorine is reduced to fluoride ion.
What does fluorine not react with?
Fast Facts: Fluorine. Fluorine is the most reactive and most electronegative of all the chemical elements. The only elements it doesn’t vigorously react with are
oxygen, helium, neon, and argon
. It is one of the few elements that will form compounds with noble gases xenon, krypton, and radon.
What group is fluorine and chlorine?
Group 7A (or VIIA) of the periodic table are the halogens: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At).
Is fluorine similar to chlorine?
What Makes Them Similar? When you look at our descriptions of the elements fluorine and chlorine, you will see that they both have
seven electrons in their outer shell
. That seven-electron trait applies to all of the halogens. They are all just one electron shy of having full shells.
What element is most chemically similar to chlorine?
halogens: Group 17 (or VII) in the periodic table consisting of fluorine (F), chlorine (Cl),
bromine
(Br), iodine (I), and astatine (At). They share similar chemical properties.
