Answer 1

Answer:

1. phosphorus(non metallic property)

2. calcium( reducing property: donor of electrons)

3.group 7A ( oxidising property: gain of electrons)

4. shielding effect

5.non metals are electronegative

6.metallic property decreases across period

7.loss of electrons is the cause of reducing property

8.non metals are good oxidising agent

9.nuclear charge increase across period

10. (b) is he incorrect statement as metals cannot have high EN value
