Which element has the same valence electrons as bromine (Br)?
The element that has the same valence electronic configuration as bromine (Br) is iodine (I). Both bromine and iodine belong to Group 17 or the Halogens in the periodic table and have seven valence electrons.
To determine an element with the same valence electrons as bromine (Br), we need to look at its position on the periodic table. Bromine is located in Group 17, also known as the halogens. The halogens have seven valence electrons, so any other element in Group 17 will also have the same number of valence electrons. Therefore, the element that has the same valence electrons as bromine is iodine (I).
To determine which element has the same number of valence electrons as bromine (Br), we need to look at bromine's position on the periodic table.
Bromine is located in Group 17, also known as Group VIIA or the Halogens. The elements in this group have 7 valence electrons. Valence electrons are the electrons in the outermost energy level of an atom, and they determine the atom's chemical properties.
Thus, any other element located in Group 17 on the periodic table, such as fluorine (F), chlorine (Cl), iodine (I), or astatine (At), would also have 7 valence electrons and the same valence electron configuration as bromine.
