Periodic trends vary as we move across the periodic table. In general, as you move across a row in the periodic table A) ionic size increases. B) atomic radius decreases. C) nuclear charge decreases. D) ionization energy decreases.
In general, as you move across a row in the periodic table, B. atomic radius decreases. This is because there is a stronger attraction between outermost electrons and nucleus, which is why the radius between them becomes smaller.
