Atomic size trend ap che8/30/2023 Based on this you could say: A) Element Z is further to the left side of the periodic table B) Element X is closer to the top of the periodic table C) Element Z and X are probably in the same group. alkali, and alkaline-earth metals, tend to be good reducing agents, as their valence electrons, whose radial orbit DEFINES the atomic radius, tend to be readily oxidized. Periodic Trends Multiple Choice Review PSI Chemistry Name Atomic Size 1) Elements Z and X are compared. ![]() On the other hand, the larger elements, i.e. Seitsonen AP, Schmid M, Varga P (2004) Visualization of atomic processes on. nitrogen, fluorine, oxygen, TEND to be very powerful oxidants, and this is also manifested by their small atomic size. J Phys Chem 88:892897 Assmann J, Narkhede V, Khodeir L, Lffler E. Excluding the Noble Gases, the smaller atoms from the right hand side, i.e. ![]() It follows that the SMALLEST atoms derive the right of the Table as we face it. Of course, the diagram shows NO data (it should do so), but the relative size of the atoms across the Period, and down the Group is clear. And the best metric that illustrates this trend is the well-known diminution of atomic radii across the Period from left to right? And of course, we should look at some data. Now it is a fact that the nuclear charge is SHIELDED very poorly by incomplete electronic shells. ![]() The chemistry and atomic structure of the elements is a contest between (i) nuclear charge, conveniently represented by #Z_"the atomic number"#, and (ii) shielding by other electrons.
