Interpretation: The term atom needs to be defined in own words.
Concept introduction: Atom is the building block of a matter. It can be further divided into 3 subatomic particles namely protons, electrons and neutrons.
Answer to Problem 2SSC
The smallest particles of elements are called atoms. The atom makes up every single object. The air and a chair both are made up of atoms.
Explanation of Solution
The basic building of matter is atoms. There are 90 natural types of atoms and 25 lab-forming atoms.
The atoms are made up of three basic particles are protons, neutrons, and electrons.
Protons: carry a positive charge
Neutrons: carry no charge
Electrons: carry a negative charge
The nucleus is a central particle of atoms, which make up by joining protons and neutrons.
- Atom is the unit of matter.
- Atom is the smallest particle of elements.
- Atoms contain particles called protons, electrons, and neutrons.
