Web7.7: Group Trends for Group 1A and 2A. The elements within the same group of the periodic table tend to exhibit similar physical and chemical properties. Four major factors affect reactivity of metals: nuclear charge, atomic radius, shielding effect and sublevel arrangement (of electrons). Metal reactivity relates to ability to lose electrons ... Web2.1. 1.9. Some of the trends in the modern periodic table with respect to group 15 elements of the p-Block elements are discussed below. 1. Electronic Configuration. The valence shell electronic configuration plays a major role in how an element behaves. The valence electron shell configuration of group 15 elements is ns 2 np 3.

WebThe elements of Group 1 and Group 2 of the modern periodic table are called S-block elements. ... It is observed that the physical and chemical properties of these s block elements change in a particular trend as the atomic number of the elements increases. ... The alkali metals have a low melting and boiling point due to the weak metallic bonding. WebSince the molecular mass and electron cloud size is in the order S 8 > P 4 > Cl 2, the melting point trend will be in that same order. We can use the melting point of sodium as a benchmark for melting points of non … WebIn the below periodic table you can see the trend of . Absolute Melting Point.
