What is the periodic trend for electronegativity across a period?

What is the periodic trend for electronegativity across a period?

Step 1: Understand what electronegativity means. It is the ability of an atom to attract electrons in a chemical bond.
Step 2: Know that the periodic table is organized in rows called periods.
Step 3: Look at a specific period (row) on the periodic table, for example, Period 2.
Step 4: Notice that as you move from left to right across the period, the elements change from metals to nonmetals.
Step 5: Realize that nonmetals generally have higher electronegativity than metals.
Step 6: Conclude that as you move from left to right across a period, the electronegativity values increase.
