Discussion of the Structure of the Atomic Nucleus

1. The atomic nucleus

Atom is the basis of matter consisting of the atomic nucleus and the negatively charged electron cloud that surrounds it. The atomic nucleus consists of positively charged protons and neutrally charged neutrons.

2. Objects with opposite charges are brought closer

Objects with the same charge will repel if brought closer, or object which have different charges will attract each other.

3. Glass and Silk

Glass and silk: electrons from the glass transfer to the silk, causing the glass to be positively charged and the silk cloth to be negatively charged

4. Static electricity

Definition Static electricity is a collection of electric charges in a certain amount that remains (static), an imbalance of electric charges in or on the surface of objects. The electric charge will remain until the object loses it using an electric current that releases the electric charge. Static electricity cannot flow from one place to another or can only exist for a moment in one place, unlike dynamic electricity.

Static electricity is a physical phenomenon that indicates the interaction between electrically charged objects. Electric charge can be negative or positive. Two objects that rub against each other will transfer an electric charge from one object to the other. An object with an excess of electric charge is called a positive charge, while an object with a lack of electric charge is called a negative charge.

5. Glass (fiberglass) and ebonite

Glass and silk: electrons from the glass transfer to the silk

Ebonite and wool: electrons from wool move to ebonite

Glass (positive charge) and wood (negative charge) will attract each other

6. Van De Graaf Generators

The Van de Graaff generator is a static electricity machine that generates very high direct current voltages by collecting electrical charges and storing them on the surface of a hollow metal ball.

7. The glass is positively charged and the electroscope is negatively charged

An electroscope is a tool that can be used to determine the type of charge on an object. So the function of the electroscope is to find out the type of charge of an object. To determine the type of charge on an object, the charge separation must be carried out by conduction so that the electroscope becomes charged.

If the electroscope is led, then it is negatively charged. Conditions that can arise when a charged object is brought close to a metal ball are as follows:

If a negatively charged object is brought close to the metal: the electrons will fall toward the leg, causing the two blades to move apart.
If a positively charged object is brought close to the metal ball: electrons will be attracted from the blade to the metal ball, so that the two electroscope blades will come closer to each other.

8. Coulomb force

Based on the Coulomb Force formula, Coulomb Force is affected by electric charges and the distance between charges

9. Cloud Electric Charge

Lightning is evidence of an electric charge in clouds. Lightning is formed from Comonolimbous clouds. Inside the cloud there are positively (+) and negative (-) charged particles. Positive particles collect at the top and negative particles gather at the bottom. Then the cloud particles rub against the air particles, so that if the electrical energy is sufficient, it is released in the form of lightning.
