An element having the atomic number 17 will resemble which of the following elements having atomic number as given below?
Answer Details
The element with atomic number 17 is Chlorine. Chlorine is a member of the halogen group of elements, which also includes Fluorine (atomic number 9), Bromine (atomic number 35), Iodine (atomic number 53), and Astatine (atomic number 85). These elements are characterized by having seven electrons in their outermost shell, which makes them highly reactive.
Of the options given, Bromine is most similar to Chlorine in terms of their chemical properties and electron configuration. Both Chlorine and Bromine are members of the same group in the periodic table and have similar electron configurations, which makes them have similar chemical properties. Both are reactive elements and form compounds with a variety of other elements, including metals, nonmetals, and other halogens.
Therefore, the element with atomic number 17 (Chlorine) will resemble the element with atomic number 35 (Bromine) the most.
