WebIn general, the atomic radius decreases as we move from left to right in a period and it increases when we go down a group. This is because in periods the valence electrons are in the same outermost shell. The atomic number increases within the same period while moving from left to right which in turn increases the effective nuclear charge.

WebAs the atoms increase in size, the distance between their nuclei also increases. With this knowledge in mind, we can follow these three steps to calculate bond length: 1. ALWAYS draw the Lewis structure for the molecule and determine the bond order. 2. Find the atomic radii of the two atoms on an atomic radius chart. 3. Add the two atomic radii ... WebJan 19, 2024 · H, F, Cl and Br are smaller than He, Ne, Ar and Kr when not bonded; Atomic size gradually decreases from left to right across a period of elements. This is because, within a period or family of elements, all electrons are added to the same shell. However, at the same time, protons are being added to the nucleus, making it more positively charged.
