Question

fill in the element in each list with the largest electronegativity: k, fr, li --> al, cl, p --> f, sb, br --> cs, ca, n -->

Explanation:

Step1: Recall electronegativity trend

Electronegativity increases across a period and decreases down a group in the periodic table.

Step2: Analyze K, Fr, Li

Li is above K and Fr in Group 1. So Li has the largest electronegativity among them.

Step3: Analyze Al, Cl, P

Cl is furthest to the right among these elements in Period 3. So Cl has the largest electronegativity.

Step4: Analyze F, Sb, Br

F is the most electronegative element overall and is above Br and Sb in the periodic - table. So F has the largest electronegativity.

Step5: Analyze Cs, Ca, N

N is in the upper - right part of the periodic table compared to Cs and Ca. So N has the largest electronegativity.

Answer:

Li
Cl
F
N
