Ответ:
group 7
Explanation:
fluorine and chlorine are gases at room temp
bromine is liquid at room temp
iodine and astatine are solid at room temp
they are all in group 7
Ответ:
Group 17 or VIIA which consists of Halogens have elements existing in solid, liquid and gas at room temperature (20 degree celcius).
Explanation:
Fluorine, Chlorine, bromine, Iodine and Astatine are the halogens we know.
At room temperature,
Fluorine and chlorine are gases,
Bromine is a liquid and
Iodine and Astatine are solids.
Halogens are called as Salt producer.
They are diatomic elements except Astatine with a subscript 2 which represents a molecule of halogen is comprised of two halogen atoms![(F_2,Cl_2,Br_2,I_2 and At)](/tpl/images/0286/6088/21766.png)
The general electronic configuration of halogen is![ns^2np^5](/tpl/images/0286/6088/d9bfc.png)
The elements present in the same group will have same number of valence electrons (outer shell electrons)
For example
Fluorine, Chlorine, Bromine are all present in the same Group
The electronic configurations are
Hence all these elements have similar chemical properties since it depends on the electrons present in an element.
