Question
All matter is made of small particles called
- Compound
- Elements
- Atoms
- Molecules
Hint:
The tiniest particle to ever exist in the universe forms matter.
The correct answer is: Atoms
- All matter is made up of small particles known as atoms.
- In this universe, every form of matter is made up of tiny particles that are indivisible to the naked eyes known as atoms. They are identical in size, mass, chemical properties, etc.
- These tiny atoms combine together to form different compounds. Atoms are chemically neutral. This is because the number of positive charges is equal to the negative charges.
The positive charge in the atom is known as proton and the negative charge is known as the electron.
