Show all of yor work for full credits. Be sure to include all proper units and pay attention to significant figures! In each of the following groups, which element is the most electronegative? K, Na, H F, Br, Na B, N, F On the basis of electronegativity, which is the more polar bond in each of the following pairs. H-F or H-CI H-CI OR H-I H-BR OR H-CI H-I OR H-Br Draw each of the following molecules using the partial positive and partial negative notation shown in class. Hydrogen chloride, HCI carbon monoxide, CO bromine monoflouride, BrF Write a Lewis structure for each of the following simple molecules. Show all bonding valence electrons pairs as lines and all lone pairs as dots. Remember resonance structures. NBr_3 HF CBr_4 C_2H_2 C_2H_6 NF_3Explanation / Answer
In a modern periodic table, the electro negativity decreases along a group from top to Bottom and increases across a period.
That means from Left to right increases and from top to Bottom decreases.
1. a . H is more electronegative because from top to Bottom, the electronegative decreases. and here all elements are in one group .
b. F is more electronegative because from top to Bottom, the elctronegativity decreases. and Left to right increases.
c. F is more electronegative because the elctronegativity increases.from left to right.
