Periodic trends in the sizes of atoms What do we mean by the "size" of an atom? The concept of "size" is somewhat ambiguous when applied to the scale of atoms and molecules. The reason for this is apparent when you recall that an atom has no definite boundary; there is a finite (...

Due to the spin of the unpaired electron in a Group 1 atom, the ground state is doubly degenerate, but the atoms in Groups 2, 12, and 18 have non-degenerate ground states. The lowest energy configurations of the atoms in Groups 13-17, on the other hand, give rise to several non-...
Trends in Atomic Size Influenced by three factors: 1. Energy Level Higher energy level is further away. 2. Charge on nucleus More charge pulls electrons in closer. 3. Shielding effect Group trends As we go down a group... each atom has another energy level, so the atoms get bigger. ...
periodic trends of atomic radii an atom gets larger as the number of electronic shells increases. therefore, the radius of the atom increases as one goes down a specific group in the periodic table of elements. the size of an atom generally decreases as one moves from left to right for a...
The size of atoms is often compared using atomic radius. The atomic radius is the distance between the center of the nucleus of an atom and the valence electrons. The valence electrons are the electrons in the energy level furthest from the nucleus. ...
