The answer is (1). The electrons transfer form one reactant to another means that there is the change of valence. For other choices, the valence of reactant does not change.
Answer:
Occurs in substances that have at least one non-metal
Explanation:
The overlapping sets which is denoted by the region B is best attributed to connote with the choice "occurs in substance that have at least one non-metal".
To form an ionic bond, a metal and a non-metal must exchange electrons in order to an electrostatic attraction to occur.
In the case of covalent bonds, non-metals shares their valence electrons to form a bond by attaining an octet configuration.
So, we see that a pre-requisite for both bonds to form is a minimum of the presence of a non-metal.
