WebDec 13, 2024 · Atomic number increases down a group, and across a period. Ionization energy is the energy required to remove a valence electron and it decreases down a group, and across a period. 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. terry s terryWebSep 16, 2024 · First ionization energies generally decrease down a column. Although the principal quantum number n increases down a column, filled inner shells are effective at screening the valence electrons, so there is a relatively small increase in the effective nuclear charge.
