The way the atomic radius varies with increasing atomic number can be explained by the arrangement of electrons in shells of fixed capacity. The shells are generally filled in order of increasing radius, since the negatively charged electrons are attracted by the positively charged protons in the nucleus. As the atomic number increases along each row of the periodic table, the additional electrons go into the same outermost shell; whose radius gradually contracts, due to t… WebJan 14, 2016 · The atomic radius is known as the distance from the centre of an atom to the boundary within which the electrons spend 90% of their time. The size of an atom decreases from left to right. This is because as the number of electrons increases, the attractive forces on each electron becomes stronger.
