Label the subatomic particles shown in Figure 4.22.
Interpretation: The subatomic particles in the given figure should be labeled.
Concept introduction:
Atom is the smallest particle in the element that can neither be created nor be destroyed. It is composed of three subatomic particles, protons, neutrons and electrons.
Answer to Problem 42A
Subatomic particle ‘a’ is electron, ‘b’ is protons and ‘c’ is neutrons.
Explanation of Solution
An atom of any element has three subatomic particles labelled as:
- Electron cloud
- Protons
- Neutrons
Electron cloud: Electron is a negatively charged subatomic particle that surrounds the nucleus in clusters. An electron is
Protons: Protons are positively charged subatomic particle present inside the nucleus. A proton is
Neutrons: Neutrons are zero charged subatomic particles present inside the nucleus along with protons. A neutron is also
Hence, the subatomic particles ‘a’, ‘b’ and ‘c’ are electrons, protons and neutrons respectively.
