In general, the EPA does not allow claims like those to be made on the productâs label. fda and cosmetics The primary responsibility of the FDA is to enforce the regulations and requirements of the Food, Drug and Cosmetics Act of 1938, which protects consumers from contaminated or misbranded (mislabeled) products.
Rating Newest Oldest. Best Answer: Krypton has 8 valence electrons. It is a noble gas, meaning it has the maximum number of valence electrons its outer shell can hold.You know because it is in group 8A of the periodic table, therefore it has 8 valence electrons. The group number tells you how many electrons are in the valence shell.:).t is a noble gas, meaning it has the maximum number of valence electrons its outer shell can hold. You know because it is in group 8A of the periodic table, therefore it has 8 valence electrons. The group number tells you how many electrons are in the valence shell. :).
Thus, its complete electron configuration is 1s2, 2s2 2p6, 3s2 3p6, 4s2 3d10 4p6, 5s2 4d â¦ 10 5p6, 6s2 4f14 5d10 6p4. From this, we see that its highest number shell, which is its valence shell is 6. Thus the valence electron configuration of polonium is 6s2 6p4.ince gallium's atomic number is 31, we know that it has 31 protons and 31 electrons. Thus, its complete electron configuration is 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p1. From this, â¦ we see that its highest number shell, which is its valence shell is 4. Thus the valence electron configuration of polonium is 4s2 4p1.
