To determine the number of valence electrons available for bonding in bromine (Br), we can refer to its position on the periodic table.
1. Bromine (Br) is a chemical element with the atomic number 35.
2. It is located in Group 17 of the periodic table, which is also known as the halogens.
3. Elements in Group 17 have 7 valence electrons because this group is one column to the left of the noble gases, which have a full outer shell with 8 electrons.
4. Therefore, it means that bromine has 7 valence electrons available for bonding.
Thus, the number of valence electrons available for bonding in bromine (Br) is seven. The correct answer is:
seven
