Question

type 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 first set (K, Fr, Li)

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

Step3: Analyze second set (Al, Cl, P)

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

Step4: Analyze third set (F, Sb, Br)

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

Step5: Analyze fourth set (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
