A student argued that electronegativity of p-block elements decrease along period and increases down the group.1. Do you agree with this? Explain. 2. Write about the metallic character of p-block elements.3. Arrange the following of p-block elements in the order of decreasing oxidising power.F2/F-( E° =+2.85 V), Br/Br- ( E° =+1.07 V), CI2 /CI- (E° =+1.36V), I2 /I- ( E° =+0.57V). |

Answer» 1. No. electronegativity of p-block elements increases along a period and decreases down a group. 2. Most of the p-block elements are nonmetallic in nature. Among p-block elements the metallic character decreases along a period and increases down a group. 3. F2 > CI2 > Br2 > I2 , because the standard electrode potential values decreases in the same order. |
