A
Electronegativity increases due to increased nuclear charge.
B
Electronegativity decreases because atoms are larger.
C
Electronegativity remains constant across a period.
D
Electronegativity increases due to increased electron shielding.
Understanding the Answer
Let's break down why this is correct
Answer
Electronegativity rises steadily as you move from left to right across a period because the nuclear charge grows while the shielding effect stays roughly the same, so the nucleus pulls more strongly on electrons. This stronger pull makes atoms more eager to attract electrons from other atoms. For example, sodium (low electronegativity) is far less eager to take an electron than chlorine (high electronegativity) on the right side of the same period. Thus, the general trend is a steady increase in electronegativity across each period.
Detailed Explanation
Electronegativity climbs across a period because each element adds a proton to the nucleus. Other options are incorrect because Students often think atoms grow larger across a period, but actually the atomic radius shrinks; Electronegativity does not stay the same across a period.
