WebA relationship is intuitively expected between electronegativity and radius: the size of an atom is determined by the distribution of electrons around its nucleus. The closer the electrons are to the nucleus, the more tightly they are bound, thus increasing the electronegativity of the atom. WebPeriod Trends. There are many trends on the periodic table. For example, ionization energy, electronegativity, and of course atomic radius which we will discuss now. Across a period, atomic radii decrease. This is because while the number of electrons increases down the period, they only add to the same main energy level, and therefore do not ...
