Why Are Fluorine and Chlorine in the Same Group

As the most electronegative element it is extremely reactive as it reacts with all other elements except for argon neon and helium. Fluorine F chlorine Cl bromine Br iodine I and astatine AtThe name halogen means salt former derived from the Greek words halo-salt and -gen formation.

Comparing Halogen Reactivity Trends With Those Of The Alkali Metals Halogens Become Less Reactive Down The Chemistry Classroom High School Chemistry Chemistry

They have similar atomic masses.

. All the three elements have 7 valence electrons and the elements having same number of valence electrons will show similar chemical properties and thus they belong to the same group. It is the lightest halogen and exists at standard conditions as a highly toxic pale yellow diatomic gas. The Group 7A elements have seven valence electrons in their highest-energy orbitals ns 2 np 5.

Draw a graph showing the change in potential energy as two molecules of fluorine get closer to each other. They have similar physical properties. There is no reaction in the dark.

Label the position where the molecules are most stable. Why is the electron affinity of fluorine is less than chlorine. Hence the correct answer is they have similar chemical properties.

The atomic size however is larger for chlorine than it is for fluorine because chlorine has three energy levels chlorine is in period 3. The fluorinefluorine bond of the difluorine molecule is relatively weak when compared to the bonds of heavier dihalogen molecules. The reason for electronegativity can be determined by the properties like atomic size interelectronic repulsion.

They have similar boiling and melting points. The bond energy is significantly weaker than those of Cl 2 or Br 2 molecules and similar to the easily cleaved oxygenoxygen bonds of peroxides or nitrogennitrogen bonds of hydrazines. They have similar reactions with other elements.

Fluorine F2 and Chlorine Cl2 both exist as diatomic molecules. Although fluoride is toxic at doses that are WAY higher than what is found in drinking water apologies to fluoride conspiracy loonies fluorine makes it seem like a baby rattle. Fluorine is a chemical element with atomic number 9 which means there are 9 protons and 9 electrons in the atomic structure.

Chlorine has atomic number 17 with the electronic configuration N e 3s 2. Compare elements on more than 90 properties. Fluorine is a group seven element just like chlorine.

Fluorine has a boiling point of -8503 K and chlorine has a boiling point of 239 K. Each group has similar. Flourine and Cholrine have similar properties because they have the same number of electrons in outmost shell 7.

The violence of the reaction drops considerably as you go from fluorine to chlorine to bromine. Fluorine is a chemical element with the symbol F and atomic number 9. In the presence of a flame the reactions are rather like the fluorine one - producing a mixture of carbon and the hydrogen halide.

Comparing Group 6 and Group 7 values. Fluorine and chlorine belongs to the same group halogens. Group 7A or VIIA of the periodic table are the halogens.

Among the elements fluorine ranks 24th in universal abundance and. Fluorine is very pale yellow chlorine is yellow-green and bromine is red-brown. The nucleus is composed of protons and neutrons.

The reactions between alkanes and chlorine or bromine. The chemical symbol for Fluorine is F. Why do fluorine and chlorine have similar properties.

They have the same number of electrons in their outer shell so they are similar in their chemical properties. Compare Fluorine and Chlorine on the basis of their properties attributes and periodic table facts. Fluorine is NOT fluoride just like chlorine a WWI chemical weapon is not chloride salt.

As you might have noticed the first electron affinity of oxygen -142 kJ mol-1 is less. The atom consist of a small but massive nucleus surrounded by a cloud of rapidly moving electrons. Iodine crystals are shiny purple - but easily turn into a.

Up to 24 cash back so fluorine and chlorine are in the same group because they have the same number of or 7 electrons in their highest energy level or outer shell if no other mark awarded allow 1 mark for have the same similar. All the elements of similar categories show a lot of similarities and differences in their chemical atomic physical properties and uses. The halogens become darker as you go down the group.

A similar reversal of the expected trend happens between oxygen and sulphur in Group 6. Why are fluorine F chlorine Cl and iodine I in the same group of the periodic table. B because the relative electrical charges are 1 for an electron and 1 for a proton allow electrons are negative and protons are positive 1 and the number of electrons is equal to the number of protons if no other mark awarded allow 1 mark for the charges cancel out 1 c the electronic structure of fluorine is 27 and chlorine is 287 allow diagrams for the first marking.

First we will see the electronic configuration of chlorine and fluorine. Now we can conclude that the ionization energy for chlorine should be lower than that of fluorine because the electron would be easier to pull off when it is further away from the nucleus. The first electron affinity of oxygen -142 kJ mol-1 is smaller than that of sulphur -200 kJ mol-1 for exactly the same reason that fluorines is smaller than chlorines.

They are in group seven because each has seven valence electrons which means each has seven electrons in the outermost layer of the atom. Complete step by step answer.
