Web10 mrt. 2024 · Therefore, the effective nuclear charge increases with atomic number across a period. The size of the atom decreases because the outer electrons are held … Web29 dec. 2024 · The effective nuclear charge experienced by an electron is otherwise called the core charge. It is mathematically evaluated as the difference in the atomic number and the core electrons. and since elements in the same group have equal number of Valence electrons, the effective nuclear charge is constant down the group. dallas county tags and registration
