1) The document discusses static electricity and electrostatics, including the structure of atoms, charges of subatomic particles, and how charge is transferred between objects. 2) It explains that rubbing two materials together can cause electrons to transfer, leaving one material with an excess of electrons (negative charge) and the other with a deficit (positive charge). 3) Unlike charges attract due to this transfer of electrons, while like charges repel, and the amount of charge on an isolated system remains constant.

2. Study of static electricity, or the
study of charges at rest.

3. atoms
consist of neutrons (no charge), and
amounts
of protons (p+) and electrons (e-)

4. Protons and neutrons
(known as ),
are found in the
nucleus and
electrons move in
around the
nucleus.

5. Nucleons
be removed.
Electrons in the orbitals
be removed when

6. All types of charges are acquired through

7. This happens when two things are rubbed
together and are

8. Positive charge forms due to Negative charge forms due to

10. Like charges repel Unlike charges attract

11. The attraction
between a charged
object and an
uncharged object.

Polarisation of insulators

15. Charge cannot be created or
destroyed, only transferred
from one object to another.

16. The nett charge on an isolated system
(charge can’t go anywhere)
stays constant during any physical process.

18. Charge on each of two identical size conductors
𝑄 =
𝑄1 + 𝑄2
2

19. Quantization of charge
Q = n·qe
An object has an electrical charge that is an
integer multiple of he elementary charge
(electron charge: -1,6 x 10-19 C).
