Non-metallic character decreases down a group because of decrease in electron affinity which is due to increase in atomic size. Log in. 13 points Why non metallic character of elements decrease down the group in p-block? I.P decreases on moving down the group because atomic radius increases. Metallic and non-metallic character : All the elements of this group are non-metal. Along a period, non-metallic character increases from left to right due to increase in electron affinity which is due to decrease in atomic size. By losing the electrons, element gains positive charge. metallic character is governed by the tendency of an element to lose an electron easily. I.P.

(i) As the effective nuclear charge acting on the valence shell increases across the period, the tendency to lose electrons decreases due to this metallic character decreases. This occurs as atoms more readily accept electrons to fill a valence shell than lose them to remove the unfilled shell. Metallic and Non-metallic Character : Group 1 to 12 are metals. Non-metallic property increases across a period and decreases down the group due to the same reason due to an increase in nuclear attractive force. Since the electrons in larger atoms are farther from the nucleus, the energy required to remove the most loosely-bound electron (its ionization energy) decreases. metallic character is governed by the tendency of an element to lose an electron easily. Thus basic nature increases down the group and acidic character decreases down the group. Metals are ductile while nonmetals are not. Explanation:As we move down a group atomic size increases.As a result the force of attraction between nucleus valence electron decreases.Hence the tendency to lose electrons to form positive ions increases hence mtallic character increases. The increase in atomic radius decreases the strong electrostatic force of attraction between the positive nucleus and the negative electrons, causing the electrons to be held more loosely. Metallic character and periodic table trends: Metallic character decreases as you move across a period in the periodic table from left to right. Due to this the nuclear force of attraction on the electrons in the outermost shell decreases because of this they can be easily lost. The effective nuclear charge experienced by valence electrons decreases because the outermost electrons move farther away from the nucleus.
