Trend in ionisation energy across period
WebAll elements have one first ionisation energy - regular atoms which don't form positive ions by test tubes. The reason that helium (1st I.E. = 2370 kJ mol-1) doesn't normally form a aggressive ion is because of the huge lot of energy that become be needful into eliminate one of its electrons. Patch of first ionisation energies in the Periodic Table WebTable 2 shows the first 6 successive ionisation energies of an element X, which is in Period 3 of the Periodic Table. • Using Table 1, describe and explain the trend in first ionisation energies shown by the Period 2 elements, Li–N. • Using Table 2, identify element X. Explain how you decided on your answer. [10] element Li Be B C N
