To determine

To complete: The sentence.

Explanation of Solution

Introduction:

Matter is composed of atoms, which are further composed of protons, neutrons and electrons.

The protons are positively charged particleswhereas the electrons are negatively charged. However, the neutrons have no charge and so are neutral.

The electrons are more tightly bounded to some atoms and molecules. When two objects are rubbed against each other, electrons transfer from one object to another, depending on the object’s affinity for electrons. The body, which loses electrons, has an excess of positive charge. While the body gaining electrons becomes negatively charged.

This accumulation of excess electric charge on an object is known as static electricity.

Conclusion: An accumulation of excess electrical charge isstatic electricity.
