Explain the trends you observed for bromine, chlorine, magnesium, sodium, and phosphorus. explain whether they matched the predicted periodic trends.

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.

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.

Maybe you should get some from your teacher and learn more so you can get your grades up and maybe study a bit more

Idon’t know what the answer is i wish i could
