They have many similarities, which is why we put them all into the same Periodic Table group. Here is a brief list:
fluorine, iodine, bromine, and astatine
they have the same number of electrons
Fluorine, Chlorine, Iodine, and Astatine. You can find this out just from looking at a periodic table. (Electrons are what create the properties of atoms). Because of electrons and how they are placed around an atom all of the elements in the same group on the periodic table (vertical column) share the same properties. If you want to learn more as to why this is the case look up more about electrons.
The number of valence electrons is seven.
My chemistry teacher always taught us Dr. HOFBrINCl H-Hydrogen O-Oxygen F-Fluorine Br-Bromine I-Iodine N-Nitrogen Cl-Chlorine
Yes. Halogen Family includes chlorine, bromine, fluorine, iodine.
fluorine, iodine, bromine, and astatine
they have the same number of electrons
Have the same properties
Chlorine ,Bromine and Iodine have same chemical properties as Fluorine.
Fluorine, chlorine bromine and iodine have seven electrons in their valence shells, and they all need one electron to have stabilized electron configuration. Therefore they are grouped in Group 17 (halogen group) of periodic table.
Fluorine and Bromine are the two elements having the same property as that of Chlorine.
bromine,chlorine and iodine do not have the same physical properties like chlorine is a greenish yellow gas,bromine is brown and iodine is purple liquid so generally they do not have the same physical properties.
Elements similar to chlorine will be located in the same group(17).
All of the atoms have the same number of protons in their nuclei.
They are all in the same column (Group 7) of the periodic table and are also known as the halogens.
Chlorine, Bromine, and Iodine. They are all in the same periodic group.
