Metal, Non-metal, reactivity

Question 1

Extraction of Metal requires oxidation or reduction process?

Answer 1

Reduction process

Question 2

Rank the reactivity of metal according to the group (Highest to Lowest)

Answer 2

Alkali Metal > Alkali Earth Metal > Group 3

Question 3

Rank the reactivity of non-metal according to the group

Highest to Lowest

Answer 3

Halogen > Group 6 > Group 5

Question 4

Rank the reactivity of Alkali metal in the same group (Highest to Lowest)

Answer 4

Francium > Cesium > Rubidium > Potassium > Sodium > Lithium

Question 5

Rank the reactivity of Halogen in the same group

Highest to Lowest

Answer 5

Fluorine > Chlorine > Bromine > Iodine

Question 6

Why the first period non-metal has higher reactivity than the fourth period?

Answer 6

because the valence electron of non-metal in the first period stay at the more inner shell compared to the fourth one, Therefore, it gains electron easier

Question 7

Rank the reactivity series

Answer 7

K > Na > Ca > Mg > Al > C > Zn > Fe > Sb > Pb > H > Cu > Ag > Au > Pt
