Here is more about the question:
An atom has 3 subatomic particles:
Proton: positively charged particles
Electron: Negatively charged particles
Neutrons: Neutrally charged particles
The nucleus is made up of the protons and neutrons, while the electrons are found outside, within the electron cloud.
Electrons are very important in bonding. It is also heavily involved in electricity. Electricity is the flow of electrons through a conductor.
Relationships in a graph:
For direct relationships, you just need to remember, when one goes up, the other one goes up too.
Inverse relationships on the other hand, when one goes up the other goes down.
If no change occurs, then we can say that there is no relationship.
