Key Insights

• 👾 Matter occupies space and is composed of molecules, which in turn are made up of atoms.
• 🫀 Atoms consist of three subatomic particles: protons, neutrons, and electrons.
• 💐 Electrons, being negatively charged, flow and constitute electric current.
• 💐 The direction of electric current is conventionally assumed to be from the positive terminal to the negative terminal, even though electrons actually flow in the opposite direction.

Questions & Answers

Q: What is matter made up of?

Matter is made up of molecules, which are composed of atoms. Atoms consist of protons, neutrons, and electrons.

Q: Where do electrons come from?

Electrons are present in every object around us. All objects contain electrons within them.

Q: What is the direction of electric current?

The direction of electric current was initially thought to be from the positive terminal of the battery to the negative terminal. However, it was later discovered that the actual flow is from the negative terminal to the positive terminal.

Q: How was the confusion regarding the direction of electric current resolved?

To avoid confusion, it was decided that the direction of current would be assumed to be the conventional current, which flows from the positive terminal to the negative terminal. This convention has been followed since ancient times.

Summary & Key Takeaways

• Matter is anything that occupies space and is made up of smaller units called molecules.

• Molecules are composed of atoms, which consist of three subatomic particles: protons, neutrons, and electrons.

• Electrons, which are negatively charged particles, flow and constitute electric current.
