Answer 1

1),3)...................

Answer 2

Changes in the Chemical Elements F - Cl - Br

1) Electronegativity decreases as you move from F to Cl to Br in the series of chemical elements F - Cl - Br [[1]].

2) The strength of the oxygen-containing acids formed increases as you move from F to Cl to Br in the series of chemical elements F - Cl - Br [[2]].

3) The strength of the non-oxygen-containing acids formed increases as you move from F to Cl to Br in the series of chemical elements F - Cl - Br [[3]].

4) Atomic radius decreases as you move from F to Cl to Br in the series of chemical elements F - Cl - Br [[4]].

5) The highest oxidation state increases as you move from F to Cl to Br in the series of chemical elements F - Cl - Br [[5]].
