The diagram shows the electron configuration of an atom of an element for the electrons in the s and p orbitals. A shaded circle is shown. There are two concentric circles around this shaded circle. The inner concentric circle has two dark shaded dots. The outer concentric circle has two dark shaded dots in the corresponding position to the inner concentric circle. The outer concentric circle also has three light shaded dots one on its left boundary, one on the right boundary and the third on the lower boundary. What is the group number of the element in the periodic table? 1 2 13 15

Listenbase your answer to the question on the information below.nuclear radiation is harmful to living cells, particularly to fast-growing cells, such as cancer cells and blood cells. an external beam of the radiation emitted from a radioisotope can be directed on a small area of a person to destroy cancer cells within the body.cobalt-60 is an artificially produced radioisotope that emits gamma rays and beta particles. one hospital keeps a 100.0-gram sample of cobalt-60 in an appropriate, secure storage container for future cancer treatment.which choice represents the correct product for the beta decay of the co-60? fe-60ni-60fe-61ni-61
