The number of valence electrons is seven.
Halogens F (fluorine), Cl (chlorine), Br (bromine), I (iodine), At (astatine)
All of the Halogens (the second column from the right on the periodic table) have 7 valence electrons. This includes -Flourine -Chlorine -Bromine -Iodine
If you mean elements, there are six members of the halogen family; fluorine, chlorine, bromine, iodine, astatine, and element 117. Element 117 has not yet been officially named. It is currently called ununseptium, Uus, which means 117.
Elements that have seven valence electrons include the halogens in Group 17 of the periodic table, such as fluorine, chlorine, bromine, and iodine. These elements are highly reactive due to their tendency to gain one electron to achieve a full valence shell.
Fluorine has the most attraction for the hydrogen electron among halogen elements because it has the highest electronegativity value. This means that fluorine has a greater ability to attract and hold onto electrons compared to other halogens like chlorine, bromine, and iodine.
Bromine has the largest atomic radius among fluorine, chlorine, and bromine. Atomic radius generally increases as you move down a group in the periodic table.
Bromine would be the least reactive out of chlorine, iodine, bromine, and fluorine. It is a nonmetal halogen that has lower reactivity compared to fluorine, chlorine, and iodine.
Fluorine has the smallest atomic radius among fluorine, chlorine, bromine, iodine, and astatine.
Any element in the halogen group will have seven valence electrons. These elements include fluorine, chlorine, bromine, iodine, and astatine.
Fluorine is the strongest oxidizing agent among the elements chlorine, fluorine, iodine, and bromine. It has the highest electronegativity and is most effective at accepting electrons in a redox reaction.
The other elements relate to fluorine are chlorine, bromine , iodine etc since they have 7 valence electrons and hence, belong to group 17
flourine, chlorine, iodine, bromine, astatine
Fluorine has greater electron affinity than bromine, or any other element.
Bromine belongs to the same family as chlorine and fluorine. They are all part of the halogen group on the periodic table.
Halogens F (fluorine), Cl (chlorine), Br (bromine), I (iodine), At (astatine)
All of the Halogens (the second column from the right on the periodic table) have 7 valence electrons. This includes -Flourine -Chlorine -Bromine -Iodine
Fluorine has the most metallic character among fluorine, chlorine, bromine, and iodine. Metallic character decreases as you move across a period from left to right on the periodic table, and fluorine is the first element in the halogen group.
