Which element has the same number of valence electrons as bromine
Chlorine is the element that has the same number of valence electrons as bromine. Both bromine and chlorine have 7 valence electrons.
To determine which element has the same number of valence electrons as bromine, we need to look at the periodic table.
Bromine (Br) is in Group 17, also known as Group VIIA or the halogens. Halogens have 7 valence electrons.
Moving across the periodic table, we find that the element directly to the left of bromine is chlorine (Cl). Chlorine is also a halogen and has the same number of valence electrons as bromine, which is 7.
Therefore, chlorine (Cl) has the same number of valence electrons as bromine (Br), which is 7.
To determine the element that has the same number of valence electrons as bromine, we need to look at the periodic table. Valence electrons are the electrons in the outermost energy level of an atom. In the case of bromine (Br), it is located in Group 7A (or 17) of the periodic table.
Elements in the same group have the same number of valence electrons. Going across Group 7A, we can count the number of elements until we find the one with the same number of valence electrons as bromine.
Counting across Group 7A, we find that bromine is the fifth element. Therefore, the element with the same number of valence electrons as bromine is Iodine (I), which is also the fifth element in Group 7A. Both bromine and iodine have 7 valence electrons.
