Classify each element below as belonging to the representative elements, transition elements, or inner transition elements. Thorium (Th) Magnesium (Mg) Copper (Cu)
2. The elements vary from metals through metalloids to nonmetals. They form halides in
oxidation states +5 and +3 and the hydrides are all toxic gases. Identify this group of elements.
Og is the noble gas after Rn. To go from [Rn] to [Og], you must fill four subshells (s, p, d, and f) with a total of 32 electrons.
Thus, the atomic numbers of sixth and seventh period elements of the same group differ by 32. To go from [Og] to the next
noble gas, however, you would theoretically fill five subshells (s, p, d, f, and g).
How many electrons are needed to fill all five subshells?

- Why it is possible to determine the charge of monoatomic ions from their position on the periodic table for s-block metals and p-block nonmetal? Explain.arrow_forwardIn the periodic table, elements are organized based on their atomic numbers and properties. One of the most significant features of the periodic table is the periodicity in the properties of elements. For example, elements in the same group often exhibit similar chemical behaviors due to having the same number of valence electrons. Consider the halogens, which include fluorine, chlorine, bromine, iodine, and astatine. These elements are found in Group 17 and are known for their high reactivity, particularly with alkali metals and alkaline earth metals, forming salts. Their reactivity decreases as you move down the group. Which of the following statements best explains the reason for the decreasing reactivity of halogens as you move down Group 17? A. The atomic radius decreases, making it harder for the halogens to gain electrons. B. The atomic radius increases, making it easier for the halogens to gain electrons. C.
