Which group from the periodic table contains two elements that exhibit +2 and +4 oxidation states? 1A, 2A, 3A, 4A, 5A, 6A OR 7A
4A.
C, Sn, Pb
That it 2A and 4A
4A.
Carbon (C), Tin (Sn), and Lead (Pb) are elements from group 4A of the periodic table that exhibit +2 and +4 oxidation states.
The group from the periodic table that contains two elements which exhibit +2 and +4 oxidation states is group 4A. The elements in this group are Carbon (C), Tin (Sn), and Lead (Pb). In the +2 oxidation state, these elements would have a charge of +2, while in the +4 oxidation state, they would have a charge of +4.
To determine which group from the periodic table contains two elements that exhibit +2 and +4 oxidation states, we need to examine the electronic configurations and trends in oxidation states of elements in each group.
Group 1A (also known as Group 1 or the alkali metals) includes elements such as lithium, sodium, and potassium. These elements primarily exhibit a +1 oxidation state.
Group 2A (also known as Group 2 or the alkaline earth metals) includes elements such as magnesium, calcium, and barium. These elements primarily exhibit a +2 oxidation state.
Group 3A includes elements such as boron, aluminum, and gallium. These elements typically exhibit a +3 oxidation state. They don't show a +2 or +4 oxidation state.
Group 4A includes elements such as carbon, silicon, tin, and lead. Among these elements, tin (Sn) and lead (Pb) can exhibit both +2 and +4 oxidation states.
So, the correct answer is 4A, which contains two elements, tin (Sn) and lead (Pb), that exhibit both +2 and +4 oxidation states.
