WebPeriodic trend of Metallic character Google Classroom About Transcript Metallic character can be measured by the ease of an element to give away its valence electrons. It depends on the valence electron’s i) effective nuclear charge (ENC) and ii) distance from the nucleus. Let's see what's the periodic trend of Metallic character. how to make an effective budgetWebEffective nuclear charge – The attractive positive charge of nuclear protons acting on valence electrons. The effective nuclear charge is always less than the total number of protons present in a nucleus due to the shielding effect. Effective nuclear charge is behind all other periodic table tendencies. joysticks oxford msWebEffective Nuclear Charge Many of the periodic properties of atoms depend on electron configuration; in particular, the valence electrons and their level of attraction to the nucleus. Valence electrons are simultaneously attracted to the positive charge of the nucleus and screened(repelled) by the negative charges of other electrons. joy sticks nintendo switchWebRule 1: Effective nuclear charge (ENC) will explain the relative size and interest in electrons for atoms and ions.
