Which one of the following statements is not correct about the trends in the properties of the elements of a period on going from left to right?

To determine which statement is not correct about the trends in the properties of elements in a period as you move from left to right, we can analyze typical trends:

1. Atomic Radius: Generally decreases as you move from left to right due to increased nuclear charge attracting electrons more closely.
2. Ionization Energy: Typically increases as you move from left to right since more energy is required to remove an electron from an atom with a higher nuclear charge.
3. Electronegativity: Usually increases from left to right, as elements tend to attract electrons more strongly in bonds with increasing nuclear charge.
4. Metallic Character: Decreases going from left to right as elements transition from metals to nonmetals.

To identify the incorrect statement, we would need to compare these general trends to the options provided. If you can provide the specific statements, I can help identify the one that is not correct!
