Does core charge decrease down a group
WebTrend-wise, as one moves from left to right across a period in the modern periodic table, the ionization energy increases as the nuclear charge increases and the atomic size decreases. The decrease in the atomic size results in a more potent force of attraction between the electrons and the nucleus. However, suppose one moves down in a group. WebNov 8, 2016 · On coming down the group, Number of protons increases → nuclear charge increases → atomic size decreases. Number of shells increases → atomic radius increases. The shielding effect increases …
