The effective nuclear charge experienced by the valence electrons of K atom if core electrons completely shielded valence electrons from nuclear charge and if valence electrons did not shield one another from nuclear charge at all.
The effective nuclear charge experienced by the valence electrons of K atom if core electrons completely shielded valence electrons from nuclear charge and if valence electrons did not shield one another from nuclear charge at all.
Definition Definition Number of protons in the nucleus of an atom. It uniquely identifies an element, as the number of protons determines the element's properties. The periodic table of elements is arranged based on increasing atomic numbers, allowing scientists to easily locate and study elements.
