WebbGoing down group 2: there are more filled shells between the nucleus and the outer electrons …. the outer electrons are more shielded from the attraction of the nucleus …. the distance between the nucleus and the outer electrons increases …. so the atomic radius increases. You might expect the atomic radius to decrease because the nuclear ...

What is the smallest element in the second period? Socratic

WebbConsequently, the smallest atom is helium with a radius of 32 pm, while one of the largest is caesium at 225 pm. The atomic radii decrease across the periodic table because as the atomic number increases, the number of protons increases across the period, but the extra electrons are only added to the same quantum shell. WebbThe greater attraction draws the electrons closer to the protons, decreasing the size of the particle. Therefore, the atomic radius decreases. Down the groups, atomic radius increases. This is because there are … Webb26 mars 2012 · Beryllium or Be is the smallest of group two. you can find atomic radius by: the farther down you go the higher it is lowest is at top and then goes to the right. so the top five lowest... siam cafe bad wörishofen
