Trends in Atomic Radii. The atomic radius of an atom id defined as half the distance between the nuclei of 2 atoms of the same element joined together by a single covalent bond. Look at the atomic radii in the following table – notice any patterns?. First ionisation energy The first ionisa tion energy of an element is the energy required to remove one electron from each of a mole of free gaseous atoms of that element to form 1 mole of gaseous Appendix B The Ionisation Energy Diagnostic Instrument (IEDI) Choose the most suitable option and the reason for your choice in each question by filling the appropriate circles in the answer sheet.

The electrons, which may be caused by irradiation or field emission, can lead to a breakdown process to be initiated. .
