Answer:
d. usually neutral
Step-by-step explanation:
The overall charge of an ionic compound is usually neutral.
There is no net charge on the compound formed by an ionic bond due to the electrical stability that is derived from this bond association.
In an ionic bond, a metal transfers some of its electrons to a non-metal. The metal is electropositive and the non-metal is electronegative.
Therefore, the result is that two ions are produced which attracts each other with an electrostatic force.
