Idenify each statement below as either oxidation or reduction. 1.

Occurs when atoms gain electrons during bonding.:

2.

Occurs when the oxidation number of an element decreases in chemical reaction.:

3.

Occurs when atoms lose electrons during bonding.

4.

F + e- -> F-

5.

Occurs when the oxidation number of an element increases in chemical reaction.:

Occurs when the oxidation number of an element increases in chemical reaction.

6.

2I- -> I2 + 2e-

Explanation:

An oxidation reaction has the following properties;

The reduction reaction is the opposite of the points mentioned above;

1. Occurs when atoms gain electrons during bonding: Reduction

2.  Occurs when the oxidation number of an element decreases in chemical reaction: Reduction

3.  Occurs when atoms lose electrons during bonding: Oxidation

4.  F + e- > F-  : Reduction

5.  Occurs when the oxidation number of an element increases in chemical reaction: Oxidation

6.  2I- > I2 + 2e- : Oxidation

answer:

technetium is the most reactive. this is followed by silver. the least reactive out of these three elements is strontium.
