Question

Explain the variation of atomic radii in the periodic table. ​

Answer 1

Answer:

Atomic radii vary in a predictable and explicable manner across the periodic table. ... 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.
