Feb 18, 2001 · Atomic radius follows periodic trends, like other atomic properties. When you go across a period to the right, atomic radius DECREASES. This happens because the nuclear charge becomes greater, and there aren't any energy levels being added, so all the electrons are being attracted closer in. However, the radius jumps in group 18, because the ... May 09, 2018 · In general, the atomic radius of an element tends to increase as you move down an element group in the periodic table. To understand why this happens it would be helpful to take a close look at the definition of atomic radius and the radius of different elements in the periodic table. 12. transition elements 13. 32 14. valence electrons 15. electron affinity 16. electronegativity 17. ionization energy 18. 3 s2 3p4 19. atomic radius 20. ion 21. Group 1, Period 7, s block 22. All three groups of elements are metals. Alkali and alkaline-earth metals are so reactive that they are not found in nature as free elements. Transition ...
