The atomic radii decreased across Period 3 and increased down Group 17. The ionic radii decreased across a period for the positive sodium and magnesium ions, increased for phosphorus, and then decreased again. The electron affinity and electronegativity increased across Period 3 and decreased down Group 17. The ionization energy increased across Period 3 and decreased down Group 17.
Explanation:

--The atomic radii diminished across amount three and raised down cluster seventeen.

--The ionic radii diminished across an amount for the positive atomic number 11 and metal ions, raised for phosphorus, then diminished once more.

--The lepton affinity and negativity raised across amount three and diminished down cluster seventeen.

--The ionization energy raised across amount three and diminished down cluster seventeen.
