Step 1:I'll solve this problem by explaining the trend in electronegativity across the periodic table:
Step 2:: Understanding Electronegativity
Electronegativity is a measure of an atom's ability to attract electrons in a chemical bond. The trend follows a predictable pattern based on atomic structure and electron configuration.
Step 3:: Horizontal Trend (Left to Right)
Loading...
As you move from left to right across a period (row) of the periodic table, electronegativity increases. This occurs because: - The number of protons in the nucleus increases - The atomic radius decreases - Electrons are pulled more strongly toward the nucleus - This results in a greater ability to attract electrons in chemical bonds
Final Answer
Increases from left to right The trend of increasing electronegativity from left to right across a period is a fundamental principle in understanding atomic behavior and chemical bonding.
