Complete the mind map on static electricity.

Here are the completed sections of the concept map:

1. Top right box (after "and NOT"):

   • $\boxed{\text{protons}}$
   • Explanation: In static electricity, only electrons are transferred between materials; protons remain in the nucleus.

2. Middle right box (after "materials with"):

   • $\boxed{\text{charges}}$
   • Explanation: After electron transfer, materials acquire an electrical charge.

3. Bottom right box (above "repel"):

   • $\boxed{\text{like charges}}$
   • Explanation: Objects with the same type of charge (both positive or both negative) repel each other.

4. Bottom right box (above "attract"):

   • $\boxed{\text{opposite charges}}$
   • Explanation: Objects with different types of charge (one positive, one negative) attract each other.

5. Left box (after "resulting in atoms becoming"):

   • $\boxed{\text{ions}}$
   • Explanation: When atoms gain or lose electrons, they become charged particles called ions.

6. Left box (after "surface of one material becoming", due to loss of electrons):

   • $\boxed{\text{positively charged}}$
   • Explanation: Losing negatively charged electrons results in a net positive charge.

7. Left box (after "surface of other material becoming", due to gain in electrons):

   • $\boxed{\text{negatively charged}}$
   • Explanation: Gaining negatively charged electrons results in a net negative charge.
