b. Ionisation energy Ionization energy is required to remove an electron from a gaseous atom or ion to form a positive ion. Across a period, the ionization energy increases, and the ionization energy decreases down a group. c. Atomic size (atomic radius) ...
18 Consecutive elements X, Y and Z are in the third period of the Periodic Table. Element Y has the highest first ionisation energy and the lowest melting point.What could be the identities of X, Y and Z respectively? A A silicon, phosphorus, sulfur B aluminium, silicon, phosphorus C ma...
Figure 4 shows a Z plot of 3rd ionisation energy values bifurcating after Y into a -Lu-Lr tranche (R2 = 0.83) and a -La-Ac branch (0.98). The trendline for -La-Ac is smoother. Figure 5 shows that a Z plot of the melting points bifurcates after Y into an -Lu-Lr (R2 = 0.72...
