QUESTION:
Place the elements in each set in order of decreasing atomic radius.a. Cl, S, Pb. Ge, Si, Cc. Ba, Ca, Srd. S, O, Se
ANSWER:Solution 64 QP:Here, we are going to write the elements in each set in order of decreasing atomic radius.Step 1:The atomic size increases from the top to the bottom in the group because the outermost electrons in each energy level are farther from the nucleus.On the other hand, across a period, the number of protons in the nucleus increases which increase the positive charge of the nucleus. Therefore, it results the electrons are pulled closer to the nucleus. Thus, the size decrease from left to the right across a period of the periodic table.
