What are groups 6a-8a classified as on the periodic table of elements?
Groups 6A and 7A are typically classified as the "chalcogens" and "halogens," respectively. Group 8A is known as the "noble gases."
Are bromine and chlorine in group 7a of the periodic table?
Bromine and chlorine are in group VII A, which could also be designated Group 7a, of the narrow form periodic table that was commonly used before 1980. Most chemists now prefer a wide form periodic table, in which these elements are in column 17.
What is 7a in the periodic table?
"A" is not used as a symbol in the periodic table. Each element is represented by a unique symbol, such as "H" for hydrogen or "Na" for sodium. If you meant "7A" as a group number, group 7A includes the halogens (fluorine, chlorine, bromine, iodine, and astatine).
What family does fluorine belong to in the period table?

Where is the bromine on the periodic table?
Bromine is in Group 7: The Halogens, below Fluorine and Chlorine but above Iodine and Astatine.
What lines can be broken down tables into groups on periodic table?
groups 1a,2a,3a,4a,5a,6a,7a,8a : elements of each group generally have similar properties do to similar #s of valence e-s.
What element on the periodic table is most radioactive and why?
7A, they are unstable, because they don't have balance number inside the protons.
How does bromine relate to the periodic table?
Bromine is an element on the periodic table. It has an atomic number of 35. It can be found near the right side of the table. Bromine is located in the Halogens group, which is group 7A or 17, and is also in period 4.
What chemical family does iodine fall under?
Iodine is in the 7A column of the periodic table, a member of the halogen family.
