Part B Mendeleev placed thallium (TI) in the same group as lithium (Li), sodium (Na), potassium (K), rubidium (Rb), and cesium (Cs). However, the modern periodic table doesn't place thallium in this group. Use the periodic table to find the properties of thallium. Explain why Mendeleev might have grouped thallium in the same group as lithium and sodium. Also explain how thallium is different from the other five elements.

Question

Part B
Mendeleev placed thallium (TI) in the same group as lithium (Li), sodium (Na), potassium (K), rubidium
(Rb), and cesium (Cs). However, the modern periodic table doesn't place thallium in this group. Use the
periodic table to find the properties of thallium. Explain why Mendeleev might have grouped thallium
in the same group as lithium and sodium. Also explain how thallium is different from the other five
elements.

A chemical reaction occurs in three stages. Each stage consists of a mix of positively and negatively charged elements. Some of those elements react by bonding together, but each pair can only consist of 1 negatively charged and 1 positively charged element. Some elements can exist by themselves without bonding with other elements. In the chemical reaction, there are 8 elements (Z, Y, X, W, V, U, T, S). In the first reaction, two pairings were made: Z bonded to T, and U bonded to X. In the third reaction, V bonded to S. The reaction only consisted of three negatively charged elements. Which of the following statements is false? Pick ONE option Y must be positively charged V must be positively charged W must be positively charged T, X, and S could possibly be negatively charged OT, X, and 5 could possibly be positively charged ►
