Question

electronegativities of the elements na, al, p, and cl follow a specific trend across trend, an electron will be most strongly attracted to
o na.
o al.
o p.
o cl.

Explanation:

Step1: Recall electronegativity trend

Electronegativity increases across a period in the periodic table.

Step2: Locate elements in periodic table

Na, Al, P, and Cl are in the same period (period 3). Na is the left - most, followed by Al, then P, and Cl is the right - most.

Step3: Determine most electronegative element

Since electronegativity increases from left to right across a period, Cl has the highest electronegativity among these elements. The higher the electronegativity, the more strongly an element attracts electrons.

Answer:

Cl
