Chapter 1, Problem 4SC
Interpretation Introduction
Interpretation:
The given statement is to be completed by selecting correct given option.
Concept introduction:
An atom is the smallest particle that cannot be divided further. A nucleus is the dense part of an atom, present at its center.
Atoms are made up of small particles called electrons, protons and neutrons.
Protons are the positively charged species and electrons are the negatively charged species.
