Since potassium is located at the start of period 3, and bromine at the end of the same period, potassium will have a larger atomic radius than bromine, and thus the largest atomic radius of the four given atoms. However, this assumes the atom to exhibit a spherical shape, which is only obeyed for atoms in vacuum or free space. The atomic radius is the size of the atom, typically measured by the distance from the nucleus of the atom to the electron clouds around the nucleus. Atomic Radius of Bromine. You will find separate sections below covering the trends in atomic radius, first ionisation energy, electronegativity and physical properties. The trend is that ionization energy increases moving left to right across the table and decreases moving down an element group.
