Question 1 The gaining of electrons from an atom or molecule is an example of:
reduction
a.
b.
adhesion
O c. capillarity
d.
cohesion
oxidation
e.

a. reduction

Explanation:

The reduction is an example of the gaining of electrons from an atom or molecule or the loss of oxygen atom from a molecule.

Oxidation and reduction always occur together so in oxidation electrons loss by one substance is fulfil by gaining electrons in reduction process.

For example: The copper ion form copper by gaining electrons and undergoing reduction.

Hence, the correct answer is a. Reduction.
