What is the trend in electronegativity across a period in the periodic table?

Step 1: Understand what electronegativity means. It is a measure of how strongly an atom can attract electrons in a bond.
Step 2: Look at the periodic table. A period is a row of elements from left to right.
Step 3: Notice that as you move from left to right across a period, the number of protons in the nucleus of the atoms increases.
Step 4: Realize that more protons mean a stronger positive charge in the nucleus.
Step 5: Understand that a stronger positive charge attracts electrons more effectively.
Step 6: Conclude that because of this increased attraction, electronegativity increases as you move from left to right across a period.
