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 ►

Look up the density of silicon and of lead in a table online. Then look up the atomic radius of silicon and lead . Then look up the atomic mass of each element (periodic table of elements). Use the atomic mass and atomic radius of each element to make an argument about density. Based on the atomic radii and atomic mass data, which element would be the most dense. Is that expectation consistent with actual density data? Use the definition of density to support your argument.
